Jean Louis Rodolphe Agassiz (1807-1873) was a prominent Swiss-born American biologist and geologist. Here are some key highlights about his life and work:

• Early Life: Agassiz was born in Môtier, Switzerland, and showed an early interest in natural history. He studied at the universities of Zürich, Heidelberg, and Munich, earning degrees in philosophy and medicine.
• Career: He became a professor of natural history at the University of Neuchâtel before emigrating to the United States in 1847. He later became a professor at Harvard University and founded its Museum of Comparative Zoology.
