Other Scientific Fields
Leidy was also a renowned parasitologist, and determined as early as 1846 that trichinosis was caused by a parasite in undercooked meat. He was also a pioneering protozoologist, publishing Fresh-water Rhizopods of North America in 1879 - a masterpiece that is still referenced today.
Leidy collected gems as well as fossils, and donated his important collection of the former to the Smithsonian before he died. At Swarthmore, he also taught a class on mineralogy and geology.

Famous quotes containing the words scientific and/or fields:
“Those Dutchmen had hardly any imagination or fantasy, but their good taste and their scientific knowledge of composition were enormous.”
—Vincent Van Gogh (1853–1890)
“I will never accept that I got a free ride. It wasn’t free at all. My ancestors were brought here against their will. They were made to work and help build the country. I worked in the cotton fields from the age of seven. I worked in the laundry for twenty- three years. I worked for the national organization for nine years. I just retired from city government after twelve-and-a- half years.”
—Johnnie Tillmon (b. 1926)
