S. F. (Samuel Francis) Aaron

Born in Philadelphia on March 5, 1862, Samuel Francis Aaron became known as an American entomologist, naturalist, and writer. Early in his career he received support from the Academy of Natural Sciences of Philadelphia through Jessup Fund scholarships, and he went on to work closely with important insect collections and scientific institutions.

Aaron served as custodian of the American Entomological Society's collection and later worked as an economic entomologist for the Philadelphia Commercial Museum. He also described insect species himself, which helped establish his reputation in American entomology.

Alongside his scientific work, he wrote popular pieces that brought natural history to a wider audience. Surviving archival records, including a scrapbook of his published writings and his 1947 obituary, suggest a career that blended research, collecting, and accessible science writing until his death on January 15, 1947.
