Naturalist, educator, and founder of the Museum of Comparative Zoology, Jean Louis Rodolphe Agassiz was born on May 28, 1807, in Môtier, Switzerland, the oldest son of prominent pastor Rodolphe Agassiz and Rose Mayor Agassiz. Growing up near Lake Morat, Louis was fascinated by fish, catching them barehanded along with his brother Auguste. Louis was determined to study science, although his family encouraged him to pursue medicine. He studied at the Universities of Munich, Heidelberg, and Erlangen, earning a Ph.D. in 1829 and an M.D. in 1830.
