Thumbnail of James Geddes

On 22 Jul 1763, James Geddes was born, an American civil engineer, lawyer and politician. In his early career, he began the manufacture of salt, in New York state. He became a justice of the peace and a member of the State assembly.

When the N.Y. State Legislature introduced a bill to fund a feasibility study for a New York State canal, it retained Judge Geddes (1808) to survey routes across the state, east to Lake Erie and Lake Ontario. On 20 Jan 1809, Geddes recommended a Hudson-Erie route to the State legislature. Funding was delayed, but construction on the Erie Canal began on 4 Jul 1817. Taking eight years to complete, it was one of the first great engineering works in North America. Close to 1,000 Erie Canal workers died of malaria in the swamps. Geddes also consulted on canal routes for Ohio.

His work is the subject of a chapter in Lives and Works of Civil and Military Engineers of America (1871). Canals may seem a quaint idea now, but you can read this chapter on James Geddes to understand what it took to provide a new water transport route from Lake Erie to the Atlantic Ocean.


Book of the Day
Flanagan's Version: A Spectator's Guide to Science on the Eve of the 21st Century

On 22 Jul 1919, Dennis Flanagan was born, the American editor who steered the Scientific Americanfor 37 years. Flanagan rescued the magazine in the post WW II years when it was failing financially. The circulation rose from 40,000 to 600,000 under his leadership. He established a new style for the magazine, by inviting scientists to write its articles, aimed at the general reader. Those writers included such eminent scientists as Albert Einstein, Linus Pauling and J. Robert Oppenheimer.

Today's book pick is: Flanagan's Version: A Spectator's Guide to Science on the Eve of the 21st Century, by Dennis Flanagan who draws on his nearly four decades of editorial experience and insight to write a survey of the achievements of science. He examines the discoveries which he believes make them the areas of most significant growth he saw in his time. Weaving together narratives which include interesting anecdotes about the scientists, the circumstances of their work, historical fact, and scientific facts, Flanagan shows how they fit together and that modern scientists are “travelers on a common road.”

It is available from Amazon, typically about New from $11.99. Used from $2.19. (As of earlier time of writing - subject to change.)

Gustav Hertz, born 22 Jul 1887, was the nephew of Heinrich Hertz. Gustav was a German quantum physicist who, with James Franck, received the Nobel Prize for Physics in 1925 for the Franck-Hertz experiment, which confirmed the quantum theory that energy can be absorbed by an atom only in definite amounts and provided an important confirmation of the Bohr atomic model.
Why was he forced to resign his professorship in 1934?
