The Society for Useful Knowledge by Jonathan Lyons

Colonial America was a place that demanded much of settlers. While many appreciated the value of book learning, many came to America because of their strong opinions about a particular book, their new home required them to focus on practical knowledge for developing land, repairing hard-to-get goods and getting the most out of one’s one labor. In The Society for Useful Knowledge, Jonathan Lyons explores this emphasis on utility and its influence on colonial science and the revolutionary generation.

Ben Franklin is the most significant figure discussed by Lyon. He developed an appreciation early in life for the value of skilled labor, he was a printer himself, and he maintained this even as he became America’s most famous scientist and the new nation’s representative in Europe. Franklin’s influence in the American scientific community was huge even though he spent years in Europe; his connections to European scientists were part of the reason for his influence at home.

Franklin and his compatriots saw a great value in encouraging and disseminating useful information in science and engineering, especially if it might increase the productivity of American agriculture and manufacturing. Franklin founded one of the earliest scientific societies in the colonies and it eventually had many imitators. He also supported the establishment of what eventually became the University of Pennsylvania, though he broke with the other organizers when his emphasis on utility conflicted with their desire to provide an education focused on classical languages in the European mold.

Though Franklin was not trying to establish institutions that would lead to the revolution, he and many who worked with him did it anyway. Franklin and his Quaker neighbors preferred education in useful knowledge and trades. Many colonial scientists were self-taught and learned on their farms and workshops. They saw little value in the classical education popular in Europe that distinguished the aristocracy and upper class from others, but did little in their minds to suit a person for a role of value in the community. Americans needed to get stuff done and they didn’t care much about a person’s pedigree. This opened up opportunities for people of low social status to grow in wealth and influence. (Even in Europe, amateur scientists from many classes were common and it especially leveled the social ground around England’s coffeehouses.)

Franklin’s circle of mechanics and part-time scientists influenced the generation that followed them. Franklin’s personal reputation allowed him to be a leader in that generation who became the founders of the United States. The emphasis on practicality and experience, with the accompanying devaluing of ancient authorities in dead languages, influenced American political thought as well as its science, technology and education. The connections he made as a postmaster and scientific communicator also formed a model for the political influencers of his time.

The Victory of Reason by Rodney Stark

Stark, Rodney. The Victory of Reason: How Christianity Led to Freedom, Capitalism, and Western Success. New York: Random House, 2005.

Rodney Stark argues in The Victory of Reason that the West grew to prominence in science, technology, commerce, and power because of its foundations in Christianity. Personal freedom, democracy, and capitalism grew and eventually flourished in Western Civilization because Christianity provided a philosophy and set of beliefs that such things were possible, achievable, and valuable. These things failed, stumbled, and declined in other parts of the world because the cultures, particularly religions, that prevailed there supported philosophies and beliefs that lead another direction.

It starts with a notion of God that is almost unique to Christianity: God is a being of reason. Therefore they could use human reason, however imperfect, to understand God and increase our understanding of Him. Christian theology wasn’t simply asserting scripture, but reasoning about God and His Word to increase, refine, and improve knowledge and doctrine.

The Christian faith embraced progress through reason in doctrine. Christians looked forward to becoming progressively better believers. God is immutable, but those who believe Him can grow in understanding as they mature and with successive generations. This religion of belief contrasted with religions of practice, which inherently looked backward to established law.

These foundational beliefs in reason and progress carried over into Christian views of the physical world. It was a real place made by God. In addition, because God created the world using His reason, we can understand it using ours, just as we can use reason to increase our understanding of God. This belief gave impetus to modern science. Some credit goes to the ancient Greek philosophers, some of who had faith in reason and others in experimentation, though not both at the same time. Islamic philosophers admired, preserved and closely studied the Greeks. However, it was Christians who took these resources and added their own worldview to create modern science. Early scientists were Christians, often supported by the church directly or through universities, which were connected to the church at the time. Western nations gained a lead in science that they still hold.

Progress carried over to social and political issues as well. In particular, Christian beliefs about human equality made the church a leader in the abolition of slavery in Europe and later the Americas. It also gave rise to increasingly democratic governments, personal freedoms, and property rights. This created an environment where capitalism could flourish. Capitalism love technological development, and it didn’t hurt that it was growing in cultures that were amenable to science, and these things grew together creating new levels of freedom, opportunity, and wealth. Christian theologians had the flexibility and reasoning power to adapt doctrine to these new developments while remaining true to received scripture.

Stark supports his arguments with examples from history. One of the more interesting things about the book is the way he compares examples from the Christian world to counterexample from other cultures, such as China or Islam. China was a prominent, technologically advance culture that did not hold its lead. Islam preserved Greek knowledge during Europe’s supposedly dark ages, but did not advance. It was the late bloomers in the Christian West who had the philosophical tools to build success upon success. He also contrasts the winners and decliners in Europe and the Americas, showing how successful and wealthy nations became that way by embracing religious liberty, democracy, and capitalism, while those that declined held to or recreated feudal systems.

Cathedral, Forge, and Waterwheel by Frances & Joseph Gies

Among many the Middle Ages, between the Classical period and the Renaissance, is still thought of as the Dark Ages.  In their book Cathedral, Forge, and Waterwheel, Frances and Joseph Gies summarize scholarship that shows that the Medieval period was one of commercial and technological advancement that welcomed invention and the dispersion of knowledge.

The authors present a history of technology beginning with the contributions of Greek and Roman civilization and culminating with European developments on the cusp of the Age of Discovery.  The period in between is sometimes called the Dark Ages because of the lack of documentary history, the loss of the centralizing influence of Roman Empire, and the loss of Greek texts and knowledge in much of Europe.  The Gieses attempt to debunk the notion that this time was “dark” in the sense of being backward, especially superstitious, and lacking in advancement in knowledge, commerce, science, and especially technology.

From a technological point of view, the Middle Ages didn’t inherit from the Greeks or Romans much more than they might have learned for more ancient civilizations.  The Greeks little esteemed the useful arts.  The Romans were very practical adopters of technology, and they certainly did things on a large scale, but their main contribution was size and organization.  Medieval Europe more fruitfully borrowed and built upon technology from China.  Ancient China had very advance technology in comparison to contemporary civilizations, and the spice trade aided the transmission of technology, in the form of both devices and ideas, from East to West.

I think some of the greatest advances in this period occurred in architecture and materials.  In architecture, builders began to move away from Roman circular arches to something more like true arches.  This, along with the flying buttress, another Medieval development, made a new architecture of more open and brighter spaces possible.

Materials greatly improved, too, especially iron.  Either directly or as an idea, iron-making technology moved from China to Europe.  The blast furnace gave Europeans the ability to make cast iron.  Though casting iron parts was in their grasp, the more significant issue was that a lot more iron could be made.  Iron tools and parts made a host of other technology practicable.

Technological changes led to cultural changes, too.  Improved applications of animal and water power to agriculture and food production led to a transition away from slavery to a serf-tenant system in which the people who worked the field had a right to portion of their production.  Agricultural surpluses led to the development of cities along with a decline of bound serfs rise of free tradesmen.  The development of manufacturing led to all kinds of trade and improvements in commercial practices including double-entry bookkeeping.

I think this book may be a good introduction to the history of technology for people seeking an entry point to the field.  It is neither too technical nor too academic in its style.  It covers a period of history that is not as well covered by other popular books.  It also acknowledges and summarizes the technology of the immediately preceding and succeeding ages, so it covers a very wide timeframe.

My Inventions by Nikola Tesla

Nikola Tesla’s autobiography, collected under the title My Inventions, originally appeared as six articles in issues of Electrical Experimenter in 1919. It is a surprisingly thin book, especially in light of the several biographies that have been written about him, and the possibly greater volumes propounding the mythology of an almost demi-god genius.

To be fair, Tesla was a very creative and productive inventor. His AC motors, and the power systems that support them, enabled a new level of industrial power and automation. In many ways it was the technological foundation of the power grid we have today.

Tesla was ahead of his time and he realized it. He knew that the success of AC motors was greatly aided by coming about at the right time. Even so, it took many years from Tesla’s design to become a prototype and for that to become a commercial product with an infrastructure to support its use. At the time he wrote My Inventions, the value and practicality of his later inventions were still hard for many to see.

One of these later inventions was the radio. Tesla didn’t use that term “radio.”  It’s probably fair to say that he misunderstood the phenomena he was working with. Even so, he could produce radio transmissions and put them to practical use. As a demonstration, he built radio-controlled boats. It’s a stretch to say that Tesla envisioned smart phones, but he foresaw the possibility of using radio to transmit many kinds of data and signals, sometimes to devices “not bigger than a watch.”

“The pressure of occupation and the incessant stream of impressions pouring into our consciousness thru all the gateways of knowledge make modern existence hazardous in many ways,” Nikola Tesla, My Inventions

These articles were written at the end of World War I. Tesla reflected on the potentials of technology in peace and war. He imagined that wireless communication could shrink the world, leading to the kind of cultural exchange, common ground and commercial connections that would reinforce peace. He also imagined a rocket that could be guided to its target by radio control or internal mechanism; we could call it an intercontinental ballistic missile (ICBM).

Though visionary, he was not an infallible genius. He held to notions of physics that were not supported even by the science of his time. He had some wild ideas about psychology, biology and other fields, though some of these were no more far-out and off the mark that many that were popularly accepted by his contemporaries.

Tesla wrote very much from his own experience and perspective. Though he speaks of his upbringing in eastern Europe, his education and his career in Europe and the United States, he spends little time reflecting on the places, cultures and broader events he experience. You’ll learn more about Tesla’s peculiar ailments than about the life of youth in late-19^th Century Croatia. Perhaps that wouldn’t have sold many issues of Electrical Experimenter.

A Professor, a President, and a Meteor by Cathryn J. Prince

A Professor, a President, and a Meteor, a book by Cathryn J. Prince, is a biography of Benjamin Silliman. Silliman helped to establish the United States as a scientific leader.

Silliman was part of the post-Revolutionary generation. His father, Gold Selleck Silliman, was a general in the Continental Army. Benjamin Silliman had hoped to make a name for himself in the law, but was persuaded by a family friend to pursue science, though it was not a career likely to lead to prominence in America.

American science was not well regarded in those days, especially in Europe. A falling star, and Silliman’s diligent and careful study, changed that.

In 1807, a large meteor fell over Weston, Connecticut. Silliman, a very young, new professor of chemistry at Yale, and his colleague James Kingsley, went as quickly as they could to the remote community. The carefully interviewed witnesses, surveyed the location of meteorites, and collected samples. Silliman took samples back to New Haven to analyze them in his lab.

Silliman helped to establish that meteors originated in outer space. Popular theories at the time were that they came for lunar or terrestrial volcanoes or somehow formed in the atmosphere. The notion that something from outer space could fall to Earth was radical.

Silliman other contributions to American science were his work as a popularizer and mentor. He was an able teacher and able to communicate science to a broad audience. His public lectures on science around the country were very popular. He also helped to train a generation of American scientists. At the beginning of his career, he had to go to Europe to study chemistry and geology, at the end of his career and budding scientist could be educated in the U.S.

Silliman’s ability to reach the people of his day was his devotion to his Christian faith. He saw no serious conflict between his religion and his science. He was able to stay out of debates with clergymen that would have brought opposition to his scientific views.

In spite of the title, I found little reason to drag the president into it. Thomas Jefferson was in office at the time of the Weston Fall. Silliman, like other New England Federalists, had little liking for his policies, nor did Jefferson much care for his adversaries in the region. In addition, the president did not highly esteem geology or astronomy, instead preferring biological sciences that he considered to have more practical application. Prince brings up these difference in the book, but they never seem to add up to a serious conflict between Silliman and Jefferson.

Empires of Light by Jill Jonnes

In the last decades of the 19^th Century, inventors and industrialists battled for dominance in the emerging market of electric energy. One of the major fronts of this conflict was the choice of DC (direct current) or AC (alternating current). Jill Jonnes explains the history of this pioneering age of electricity in Empires of Light.

Thomas Edison was a major player in the early days of electrification. He is known for developing a commercially viable incandescent light. The innovation that made his light commercially successful was that he developed an entire system for generating a distributing electric energy to make those lights work.

Edison designed a DC system, and he was a major proponent of DC. A weakness of his system was distance. He could only supply power over a distance of about a mile. If large areas were to be lit, a power station would be needed every mile. This made it hard for Edison to market the system for community lighting, though he successfully sold many systems to manufacturers, commercial establishments and very wealthy homeowners. In spite of the limitations, he built a system to light a portion of Manhattan; his Pearl Street station began powering lights in 1882.

Though it was not obvious at first, it soon became clear that high voltage AC could be transmitted over very great distances. The invention of transformers in Europe provided a way for voltage to be stepped up for transmission and stepped back down to levels appropriate for lighting.

George Westinghouse adopted the AC system. The advantages of AC soon make Westinghouse Electric Company a major competitor with Edison. Even Edison’s own salesman began to ask for an AC system to sell, though he was reluctant to have any involvement with AC.

Edison believed that AC and the high voltage used for its transmission were dangerous. He also had business and personal reasons to oppose the introduction of rival systems. He attacked the use of AC. He even went so far as to aid an AC opponent who successfully lobbied to make electrocution by AC power the official means of executing condemned prisoners in the state of New York.

Westinghouse pressed on and won high profile contracts that proved the safety and efficiency of his AC equipment. Notably, he had the major lighting contract for the White City of Chicago’s World Columbian Exposition of 1893. He also won the contract to build generators for the hydropower plant at Niagara Falls. The promise of inexpensive power drew major manufacturers to the area before the plant starting operating in 1895. This surprised the investors, who had though the city of Buffalo would be the target market.

Though transformers made AC a very viable system, it had other technological hurdles, such as difficulty powering motors. Serbian-born inventor Nikola Tesla solved this problem with his induction motor. Like Edison, Tesla invented an entire system for supplying electrical power to his motors, which could also easily accommodate incandescent and arc lighting. The Niagara Falls system was based on Tesla’s patented technology.

Tesla went on to invent and explore the potential of other electrical devices, notably fluorescent lights and radios. Unfortunately, he was never able to create commercial products from these later works. He fell on hard times and was quite poor for many of the last years of his life. He died in 1943.

After the formation of General Electric, which largely pushed him out of the management of the company, Thomas Edison moved on to other things. His later ventures were of mixed success, but his work on the phonograph and improvements to motion picture helped to launch the American entertainment industry. Edison passed away in 1931, semi-retired in Florida.

Westinghouse continued to grow his electrical empire. After the Panic of 1907, in which a banking crisis shook the economy, investors forced him out of the management of Westinghouse Electric. He had four other companies to run. He didn’t care for the way Wall Street did business so he got involved in Progressive politics. He died in 1914.

Jonnes includes a chapter that is a very good, brief introduction to the history of electrical science. She describes the discoveries of William Gilbert, Stephen Gray, Andreas Cuneus, Benjamin Franklin, Alessandro Volta, Sir Humphrey Davy, Hans Christian Oersted, André Marie Ampère, Zénobe-Théophie Gramme and Michael Faraday.

Canals and Their Architecture by Robert Harris

Harris, Robert. Canals and Their Architecture. New York: Frederick A. Praeger, 1969.

Water has always been an important part of human life. Drinking water is a necessity, but that is only the beginning of our uses of it. Water is also an element in agriculture, industry, transportation and commerce.

It is water’s role in transportation and commerce that Robert Harris focused on in Canals and Their Architecture. At times, artificial or modified waterways have been major means of transporting products in bulk.

Harris mentions canals from continental Europe and North America, especially the United States, but his book is mainly about the canals of Britain. This is an appropriate focus because the canal boom in Britain both fed and was fed by the Industrial Revolution that started there.

The boom began with the Duke of Bridgewater’s famous canal, construction of which began in 1760. The duke owned coalmines and wanted a cheaper way get coal to the mills and factories in Manchester. The canal was by no means an easy or inexpensive project, but it was greatly successful and the wealth put into it was regains many times over.

Bridgewater recognized the talents of millwright James Brindley, who went on to become the most prominent canal engineer of his day. Harris discussed the works of several British engineers who were successors of Brindley including Thomas Telford, John Rennie, and William Edwards.

As the title of the book suggests, it is organized mainly by the types of structures found on canals. In addition to the canal cut, Harris wrote about bridges and auqueducts, locks , tunnels, boats, buildings and unique ways of handling elevation changes on a canal route. Early canals followed the contours of the land to avoid the use of expensive and complex equipment and, where needed, were crossed by utilitarian bridges of wood or brick. As canals became straighter, and more lucrative, they added locks and other mechanisms for raising and lowering boats. The materials became more varied and complex, including stone and iron. Spectacular aqueducts carried canals over low lands. Tunnels were well-made features of canals early on because the technology for building them was readily adapted from mining.

The older canals are impressive in that so much was done with manpower and simple tools. As canals aided other industries, the improvements those industries spawned, especially in iron construction and railroads, returned to canals and the way they were made. The construction of modern canals is the work of enormous equipment.



Canals and Their Architecture includes many illustrations and photographs. These are very helpful for the laymen to see the types of structures discussed in the text, though even an engineer familiar with the terms will likely appreciate the images.

The Explorer King by Robert Wilson

Clarence King was probably the most well-known American scientist of his time. It doesn’t hurt that his scientific reputation was built on exploration of the then still wild west of the United States of that he could spin a tale. Robert Wilson recounts the life of the accomplished geologist in The Explorer King.

King was born in 1842. He was raised in Newport, Massachusetts. He was educated at Yale’s Sheffield Scientific School.

As a young man, King was enamored of art critic John Ruskin. Ruskin thought the rugged Alps of Europe to be the best subject of art for their beauty, colorfulness, ruggedness and variety. When he met western geologists and mountaineers through mentors at Sheffield, he wanted to be part of it.

He headed out for California in 1863 and became part of the state’s geologic survey. He would spend the next decade studying the geology and geography of the American west, especially its mountains. He showed great physical prowess and courage as a mountaineer.

After working on the California survey, he went on to lead surveys. In 1864, he was chosen to lead a survey of Yosemite.

He built on his reputation from the Yosemite survey to lobby Congress to fund a survey of the 40^th Parallel, roughly the route the transcontinental railroads would follow. Though it was under the auspices of the Army Corp of Engineers, it was the first federally-funded scientific endeavor that was completely staffed by civilians. While working on this survey, he was the first to discover active glaciers in the U.S. His team published new methods of silver smelting to make the mines for productive (the survey’s first report dealt with mining in order to show the commercial value of their research to money-conscious Congressmen).

The 40^th Parallel survey made King famous, though not because of the many contributions to science that came from it. King’s team heard rumors of a diamond discovery in Colorado. It would have been very embarrassing for them to have walked over such a valuable mineral resource without observing it. They tracked down the site of the discovery and determined it was a hoax; the site had been planted with rough diamonds and other uncut gemstones that the con men had bought mostly with money from their marks. Stories of massive fraud sells newspapers, especially when the names of big money men in San Francisco and New York are attached to it. King was the hero of the story.

When the U.S. Geological Survey was created, King was appointed to be its first director. His career as a scientist was already on the decline. He would turn his attention to making money in mining, but he would not be successful. He would have no money when he died.

This leads to an interesting point about King, though it is not the focus of Wilson’s biography. King had nothing to leave for his secret family. He was married to a black woman. This was a very unusual thing at the time. To protect his reputation, he kept the marriage a secret. He did not even reveal to his wife his real identity until shortly before he died (she knew him as James Todd). His friend John Hay provided for Ada Copeland Todd (and the five children she had with King) after King died in 1901.

1939 by David Gelernter

I’ve been time traveling.  I went back to visit the 1939 World’s Fair in New York.  I tagged along with a couple of locals, both to New York and 1939, Mark and Hattie.  I was looking forward to it because, like me, Mark studied engineering and is attending the fair for the first time.  I wondered how he might react to the visions of future technology on display, like the superhighways anticipated by Democracity and the Futurama (which I read about in The Big Roads by Earls Swift).  I grew up in an era of Interstates, commuting, and electrified kitchens, so the even the visions of the future on display at the fair are the past to me.

I also time traveled to 1995 to take a look back at the fair with Hattie.  I was reintroduced to her by a computer science professor.  (The professor was David Gelernter.  This is a review of his book, 1939: The Lost World of the Fair.)  Back then I was starting my career in Kansas City, so I didn’t worried about running into myself in New York.

I was fascinated by what I saw of the fair.  These people had a vision of the future.  It might seem modest to us, but it was big to them.  They dreamed of the good life in which many more people owned homes in pleasant suburbs, drove to work in their own cars on broad roads, had enough to eat, and were relieved from drudgery by electric appliances.  Within a generation, in spite of the difficulties of a major war, they largely brought their dream into reality, and we have fitfully enjoyed the results.

Gelernter compares the fairgoers to Moses looking into the Promised Land (an apropos analogy considering he also writes about what it was like to be Jewish in America at the time).  Their vision of a land of milk and honey is very much the time we live in.

This leads to one of the many points of comparison Gelernter draws between that generation and ours.  They had drive, even a kind of joy, because they had a goal toward which to strive.  The cultural angst that began to show in the 1960s is in part a sign that we had arrived.  Our goals were achieved and we hand no reason to strive, so we lost our way.  We perish for lack of vision.

I find Gelernter to be a pretty good critic of technology.  You might expect a computer science professor to be enthusiastic about the changes computers have wrought.  He is more impressed with the improvements made by that older generation.  He looks at roads and refrigeration and the host of other mid- to late-Twentieth Century technologies and sees that they made improvements to human health and happiness.  The differences made by computers pale in comparison. I can remember that in 1995, I could cut up documents with a pair of scissor, tape pieces of them together, mark the mess up by hand and give it to a person in the office we called a clerk.  A short time later, the clerk would bring me back a freshly-printed, neat document, a final version of what was represented by my taped-together prototype.  The clerk would even do a little copy editing.  When a computer can do that, I’ll be impressed.  In other words, I think Gelernter’s critique holds water even 17 years later.

Gelernter may be glad that I got the sense of time travel for which he was going.  He might be disappointed that I didn’t like Mark and Hattie much.  I slipped away from them as much as I felt I safely could.  I wanted to see the fair, and though it may seem hardhearted, I had little interest in the ups and downs of their romance or their fretfulness over the war in Europe.  I think someone could write a good novel about this couple and how the day they got engaged at the fair became a touchstone for Hattie even decades later.  If I had expected a novel, I might have liked these characters, but I was expecting a history, and I found them distracting.

Pauline Letters

The apostle Paul wrote most of the New Testament.  His letters to the early churches mix doctrine, biography, advice, and personal messages.  Paul was Jewish and belonged to a sect of zealots called the Pharisees.  He was an up-and-comer with a prestigious education and leadership roles beyond what was typical for a man his age.  He prosecuted the early church, especially congregations of Jewish converts to Christianity.  He gave it all up, though, after having a vision in which he was confronted by Jesus Christ and he eventually became a missionary and apostle to the Gentiles, planting churches in Europe and Asia.

Several themes recur in Paul’s letters.  Some of these are: the Gospel and doctrinal purity, Christian living, and relationships.

The Gospel

Paul was a preacher of the Gospel.  He frequently reminded people to remember and stick to the Gospel he taught with directness and simplicity.  There were a lot of false teachers who taught alternatives, often to draw followers and enrich themselves.  In Paul’s teaching, everything depended on Christ and what He accomplished through His life, death and resurrection; nothing could be added or subtracted from it.

Of course, some tried to add or subtract.  Some of the teachings Paul opposed were Judaizers, Gnostics, and legalism.  Judaizers proposed that to be Christian, one must be Jewish first.  This included conversion to Judaism, including circumcision, and observance of the law of Moses.  According to the Gospel, everything needed was satisfied in Christ.  The Gnostics came from the tradition of mystery religions, taught “secrets” and proposed a Christ who was resurrected as a spirit.  Paul would have none of that either.  The Gospel was plain and all significant events of Christ’s life for our salvation were publicly known, including his physical resurrection.  Both of these groups touched to some degree on legalism.  People wanted to establish rules to live by, either to control people or to aggrandize themselves or to suggest people had a part in their own salvation.  Paul’s Gospel asserted that Christ is all, His sacrifice atoned for our sins and His power in us enables us to do good.

Christian Living

If Christianity wasn’t about following rules, how were we to live?  Could we do whatever we wanted?  Of course, it is silly to think that God would save us from our sins just so we could do whatever evil came to us.  It was equally naïve to think we could, on our own, live up to any rule that is truly pure and perfect.

Instead, a Christian life should be typified by love, humility, gratitude, and obedience to God.  We are to honor Christ our rescuer by imitating Him.  This isn’t to win his favor, but to return the love He showed us and express gratitude for the mercy we did not deserve.  Christ empowers us to live in a new way, knowing Him and doing good instead of sinning and becoming more estranged from God.

Relationships

One of the most important ways we can show our love for God and be Christ-like is in our relationships with others.  Paul wrote about all kinds of relationships: marriage, parent-child, employer-employee (in those days sometimes master-slave), and fellow in the church.  We should treat others with the love, kindness and generosity that Christ shows to us, especially in the church.

The Pauline Letters appear in most Bibles generally from longest to shortest: Romans, First Corinthians, Second Corinthians, Galatians, Ephesians, Philippians, Colossians, First Thessalonians, Second Thessalonians, First Timothy, Second Timothy, Titus, and Philemon.  First and Second Timothy, Titus and sometimes Philemon are called the Pastoral Letters because Timothy and Titus were young pastors.

The Brooklyn Bridge by Judith St. George

St. George, Judith. The Brooklyn Bridge: They Said It Couldn’t Be Built. New York: Putnam, 1982.

Published shortly before the centennial of the Brooklyn Bridge, this book is a short history of bridge. The story of the bridge is necessarily the story of the Roeblings, the family responsible for designing the bridge and overseeing its construction.

When the builders completed the bridge in 1883, it was at the end of 14 years of construction. The plan for the bridge went back further to 1857 when engineer and German immigrant John Roebling first proposed a bridge across the East River to connect New York to Brooklyn. At the time, the only communication across the river was by ferry. Roebling was the leading suspension bridge engineer in the United States.

The bridge would not get needed support until after the Civil War. In the mean time, Roebling’s son Washington would be come a skilled engineer in own right, studying Rensselaer Polytechnic Institute, getting a practical education working with his father and studying bridge-building techniques in Europe in the company of his wife, Emily. He also was trained in leadership, having risen to the rank of colonel in the Army during the Civil War.

The bridge took a great toll on the Roeblings. John was killed by tetanus early in the development of the project. Washington’s health was ruined by caisson’s disease (the bends) and for many years Emily acted as his hand, feet, eyes and ears on the bridge project.


St. George’s brief book is a quick read, but for its brevity still a good overview of the bridges development and construction. It includes several photos and illustrations. It seems suitable for younger readers, but is not too simplistic for an adult reader who wants a quick introduction to the bridge and its early history.
