John Gossweiler

Johannes Gossweiler ComIC (24 December 1873, in Regensdorf – 19 February 1952, in Lisbon) aka John Gossweiler or João Gossweiler, was state botanist to the Government of Angola from 1899 until his death. He made important collections in every district of Angola and created the first phytogeographic map of that country. His collections of African plant specimens were sent regularly to Lisbon (Jardim Colonial and Jardim Botânico da Universidade), the British Museum, the Royal Botanic Gardens, Kew, and the University of Coimbra. Duplicates were also kept at the Herbarium of the Instituto de Investigação Agronómica in Angola. Today, many herbaria contain specimens he collected (see #Collections in herbaria).
