Hoosier paleontologists

Charles Schuchert

Schuchert was a prominent paleontologist originally from Cincinnati Ohio. As a geologist he was largely self-educated and started his career illustrating fossils for early geological surveys. He later worked as a preparator at Yale University, then worked at the US Geological Survey before joining the faculty at Yale, where he remained the rest of his career. He was president of the Geological Society of America (1922). The Schuchert Award is given by the Paleontological Society in his honor to a person under 40 whose work reflects excellence and promise in the field.
