Leo Lesquereux - 1873

Leo C. Lesquereux (1806 -1889) pioneered the study of Florissant fossil plants.

Although he is not known to have visited Florissant valley, he received fossil plants from the Hayden Survey, the Princeton Scientific Expedition, and some fossils purchased by Samuel Scudder from Charlotte Hill.
