About the author
Born in Salins, in France's Jura region, Jules Marcou trained in France and developed his geological interests through work in the Jura Mountains. Early in his career he was associated with major European scientists including Jules Thurmann and Louis Agassiz, experiences that helped launch his work in stratigraphy, paleontology, and large-scale geological mapping.
Marcou traveled to the United States in the late 1840s and became an important figure in 19th-century geology on both sides of the Atlantic. He is especially remembered for publishing an early geological map of the United States in 1855, and later a geological map of the world. His work ranged widely across Europe and North America, and he wrote extensively on rock formations, fossils, and the structure of the continent.
He spent his later years in Cambridge, Massachusetts, where he died in 1898. Remembered as a French-Swiss-American geologist, he left behind a career shaped by ambitious scientific travel, major mapping projects, and a willingness to challenge other geologists when he thought the evidence pointed elsewhere.
