Jules Marcou
French geologist (1824-1898)
Jules Marcou (April 20, 1824 – April 17, 1898) was a French-Swiss-American geologist.
Biography
He was born in Salins, in the département of Jura, in France. He was educated at Besançon and at the Collège Saint Louis, Paris. After completing his studies, he made several trips through Switzerland to recover his health. These travels led him to devote himself to natural science. During these travels, he met Jules Thurmann (1804–1855), who introduced him to Louis Agassiz.
During 1845, he worked with Thurmann on a geological survey of the Jura mountains. He was appointed assistant of the mineralogical department of the Sorbonne in 1846, and also classified its collection of fossils. During this time, he conducted geological investigations in various parts of Europe. In 1847 he went to North America as traveling geologist for the Jardin des Plantes, charged with studying the United States and the English possessions in North America.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
