August von Pelzeln

August von Pelzeln (10 May 1825, Prague – September 2, 1891) was an Austrian ornithologist. He was a grandson to novelist Karoline Pichler (1769-1843).
He studied at the University of Vienna, later working as an assistant under helminthologist Karl Moriz Diesing (1800-1867) in the Hof-Naturalien-Cabinet (from 1851). In 1857 he acquired curatorial duties formerly held by Johann Jakob Heckel (1790-1857), and subsequently became in charge of the bird (1857) and mammal (1869) collections. He worked on the birds collected by Johann Natterer in Brazil (343 species).
He was forced to retire from the museum due to ill health, and died at Oberdöbling near Vienna.
Some birds described by Pelzeln are red-eyed thornbird, spot-winged antbird, red-legged tinamou, short-billed leaftosser, yellow-margined flatbill and the New Zealand rockwren.
His name is associated with Pelzeln's tody-tyrant (Hemitriccus inornatus). Gustav Hartlaub (1814-1900) named the Madagascar grebe (Tachybaptus pelzelnii) in his honor; Otto Finsch (1839-1917) named the Pohnpei starling (Aplonis pelzelni) after Pelzeln.
