Karl Hoffmann (naturalist)

Karl Hoffmann (7 December 1823 – 11 May 1859) was a German physician and naturalist.
Hoffmann was born in Stettin and studied at Berlin University. In 1853 he travelled to Costa Rica with Alexander von Frantzius to collect natural history specimens. With his wife, Emilia Hoffmann, he settled in San José, where he operated a consultation clinic and small pharmacy from his home. In order to supplement his income, he sold wine and liquor. He served as a doctor in the Costa Rican army during the invasion of William Walker in 1856. He died of typhoid in Puntarenas.
Hoffmann is commemorated in the names of a number of animals, including Hoffmann's two-toed sloth, Hoffmann's woodpecker (Melanerpes hoffmannii), the sulphur-winged parakeet (Pyrrhura hoffmanni), Hoffmann's antthrush (Formicarius hoffmanni), and a millipede Chondrodesmus hoffmanni (Peters, 1864).
