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.

Rising Tide by James M. Barry

The Mississippi River is powerful. I’ve seen it. I grew up in the northern tip of the river’s delta and now live near one of its major tributaries. John M. Barry’s history of the 1927 flood of the Mississippi, Rising Tide, is only partly about the power of the river. It is more about the power of men, particularly the political power of the men who have tried to exert control over the river.

The first political battle related to the river took place in the 19^th Century. It was a conflict between the nation’s military engineering establishment and their increasingly influential civilian counterparts over who would control Mississippi River policy. The principal actors and figureheads for the two sides were Andrew A. Humphreys, chief of the U.S. Army Corp of Engineers, and James B. Eads, St. Louis-based civil engineer. The Corp largely won this battle, maintaining a controlling voice in river policy, but the resulting agency, the Mississippi River Commission, adopted a theory of practice that neither Humphreys or Eads supported. It would lead to floods on the river becoming increasingly bad.

That conflict doesn’t completely disappear, but it is overtaken by the greater flow of money, politics, society, and race, mostly centered in New Orleans, Mississippi’s Yazoo Valley, and Washington, DC. It is hard to give each player his due in a brief review of Barry’s book. Barry focuses on Leroy Percy, who had great influence on river policy before, during and after the flood. He was a planter in the Mississippi-Yazoo Delta and, briefly, a U.S. Senator from Mississippi. He was also a relative of Walker Percy, one of my favorite authors.

The flood made political careers and had lasting effects. President Calvin Coolidge appointed his Secretary of Commerce, Herbert Hoover, to lead relief efforts after the flood. The publicity and public goodwill that accrued to Hoover during this period helped to usher him into the White House as Coolidge’s successor. Hoover’s lack of follow-through on promises to black leaders created a crack between in the relationship between African-American’s and the Republican Party that led to a serious split.

Huey P. Long also owed some of his success to the flood and its aftermath. New Orleans business leaders promised to provide relief to neighbors who would be flooded by the dynamiting of levees to protect the city. Afterward, these men did everything they could to minimize their liability and did not even pay one-tenth of the cost of damages caused by the flooding. Long rode a wave of resentment against New Orleans aristocrats into the Louisiana governor’s office. Once there, he used his position to strip the New Orleans elite of as much power as he could. As the city elites became more insular and focused on protecting what they had, rather than growing their businesses and community, New Orleans lost its position as the leading city of the South as other more welcoming cities grew.

The Power Makers by Maury Klein

Maury Klein’s book The Power Makers is a history of power from the Thomas Newcomen’s steam engine to the foundations of America’s electric grid.

Unlike many historians who look at the history of electric power, Klein gives a lot of attention to steam. We haven’t had steam engines directly powering industrial plants for decades, but steam turbines are still central to the production of most electricity in the United States. Even nuclear power plants use steam turbines to run their generators, they just use the heat from nuclear reactions rather than from the combustion of coal or natural gas to boil water and heat the steam to more than a thousand degrees.

Klein gives attention to many lesser known names in the history of power. He shows that Thomas Edison and George Westinghouse had rivals other than each other, such as Elihu Thomson. Nikola Tesla is well known as the genius who invented the AC motor, but other engineers helped develop his prototype into a commercial product, such as mathematically talented engineer Benjamin Lamme. Many talented inventors tried their hands at making electric lighting and power systems better. Only some of them had the vision, business sense, good partners and luck to turn their ideas into successful products. Few of them are widely known today.

Electrification had clear, direct effects in industry and transportation. Klein discusses how it’s influence reached into other sectors of the economy. Corporate management and finance changed to meet the needs of a growing new technology. For instance, Edison General Electric was able to take advantage of a new New Jersey law that allowed corporations to own businesses in other states. Electric companies grew, expanded and consolidated through numerous mergers and acquisitions. They had a demand for capital that nearly rivaled the railroads, another transformative technology that had shortly preceded electric power.

As the availability of electricity grew, certain industries were able to grow, too. Some chemical and metals manufacturing required abundant electric power to catalyze chemical reactions or generate the high temperatures of electric furnaces. Manufacturers flocked to Niagara after a lager hydroelectric power station started operation there in 1895.

Klein brings the many thread of his story of power together by reflections on three great fairs: the 1876 Centennial Exhibition in Philadelphia, the 1893 Columbian Exposition in Chicago and the 1939 New York World’s Fair. In the first, a giant steam engine that powered exhibits by means of belts and pulley was a significant attraction. By the second, electricity was on display, and the White City fairground was a model for testing AC power systems. By the 1939 fair, large power utilities of the type we would recognize today were becoming common. By then it was no big deal to flip a switch or pull a lever and get power so, unlike the previous to fairs, no dignitary undertook a show of doing it; the power was on from the start.

The Big Roads by Earl Swift

Swift, Earl.  The Big Roads: The Untold Story of the Engineers, Visionaries, and Trailblazers Who Created the American Superhighways.  Boston: Houghton Mifflin Harcourt, 2011.

The American interstate system is often thought to be a product of the Eisenhower administration.  It’s named for him.  However, the nearly 47,000 miles of interstate were conceived largely before Eisenhower’s presidency.  Even as he observed the Army’s 62-day, cross-country convoy of 1919, engineers were laying the political and technical foundations of national highways.  Earl Swift tells this longer history of the interstates in The Big Roads.

When Americans began calling for better roads, the typical road was mud.  The loudest calls for better roads at the beginning of the 20^th Century were cyclists, especially the colorful Carl Fisher.  Fisher’s most famous work is the Indianapolis Speedway, where a popular 500-mile race continues to be run.  His promotion of the Lincoln Highway, the first coast-to-coast highway (at least on paper), provided an important antecedent to the interstates.

The Lincoln Highway Association operated on a system that informed later highway development.  Rather than build a huge new highway, it selected existing roads for improvement, joining them together in a highway.  New roads were built only if necessary.  The association, a private organization that raised private funds for road improvement and route promotion, was a model for later systems in another way.  The Lincoln Highway was built and improved in pieces by a number of local and state agencies.  The association provided a route, coordination, promotion, encouragement, and sometimes funding, but the road improvements were mostly local works.

Thomas MacDonald, an Iowa highway engineer, was using a similar model as he worked for that state.  He worked with city and county road departments to coordinate improvements leading to a statewide system of decent roads.  When he became director of the Office of Public Roads, he brought this model to the federal highway program, institutionalizing it in the Federal Aid system that began in 1916.

Of course, the U.S. highways that developed under this system were not like modern interstates.  They were open to anyone along them.  In rural areas, they might have been and often still are long ribbons of pavement crossed by the occasional farm road.  In cities, they became crowded with business, especially restaurants and gas stations, that slowed traffic to a crawl.  This problems gave rise to the concept of a limited-access highway, first proposed by Benton MacKaye, the conservationist who conceived the Appalachian Trail.

MacDonald and his engineers began working the concept.  His office produced a report, authored primarily by Hubert Sinclair Fairbanks, that laid out most of the current interstate system in 1938.  Fairbanks supported that idea that better roads might solve problems related to slums and blight in cities.  The recommendations of this report and a follow-up commission were largely implemented in law in 1944, when the term “interstate” first appeared in legislation.

The plans for an interstate system languished during World War II and the years immediately following.  Eisenhower comes into the picture at this time because he strongly supported funding for the interstate system.

Highway engineers saw themselves as providing a good and giving the people what they wanted.  Along the way, as Fairbanks suggested, they could clean up the cities.  As they began to implement their plans in earnest, opposition arose.

Swift gives particular attention to two interstate opponents.  Critic Lewis Mumford provided the intellectual and philosophical foundation for the Freeway Revolt.  Joe Wiles, a black professional and veteran, organized opposition to Interstate 70 in Baltimore which resulted in changes to the plan and help unite the white and black communities in that city.  The federal and state governments began to take seriously the possibility that interstates could have a negative impact on the communities near them

The intestate system, finally completed in the 1990s, is the largest public works project in history.  Now that it is built, it needs to be maintained.  It will be expensive: $225 billion a year for the next 50 years to keep it in good shape.  That is more than twice what we’re spending.  In addition, improved fuel efficiency and reduced driving prompted by the economic downturn has reduced gas tax revenues for the Highway Trust Fund.  In the near future, we may need to find new ways to pay for maintaining our transportation marvel.
