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]
