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.

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 40th 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 40th 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.
