About the author
Born in Canandaigua, New York, in 1857, John Mason Clarke studied at Amherst College and began his career as a teacher before moving fully into geology and paleontology. He became closely associated with New York’s scientific work in the late 19th century, especially through the State Museum and Geological Survey.
Clarke was known for his research on Paleozoic life, including important work on Devonian fossils. Over time he rose from assistant state paleontologist to State Paleontologist, and later State Geologist and director of the New York State Museum, where he helped expand the museum’s scientific and educational role.
He died in 1925, but his name remains well known in American earth science. His legacy comes from both his published research and his long effort to build institutions that made geology and paleontology more visible to scholars, students, and the public.
