Charles Frederic August Schaeffer

Charles Frederic August Schaeffer (12 June 1860 – 29 August 1934) was an American entomologist who specialized in beetles, particularly chrysomelids and weevils. He described 109 species in 91 genera and some species like Taphrocerus schaefferi Nicolay & Weiss were described from his collections and named after him.

Schaeffer was born in London to Karl August Wilhelm Ferdinand Schäffer, a native of Prussia, and Charlotte Ernestine Dorette Koch of Hannover.^[1][2] When the family returned to Germany, he was educated there and became interested in insects at a very young age. He immigrated to the United States in 1886 and became a U.S. citizen in 1898.^[3]

He was one of the founding members of the Brooklyn Entomological Society in 1892. He was an active member of the group and in 1898, he became an assistant to William Beutenmuller of the American Museum of Natural History, becoming a curator in 1902 at the Brooklyn Museum Institute of Arts and Sciences. He made numerous collecting trips mainly in Mount Mitchell, North Carolina; Lower Rio Grande Valley, Texas (Esperanza Ranch east of Brownsville); and the Huachuca Mountains of Arizona. He described numerous species in his publications.^[4][5][6]
