Johannes Paulus Lotsy

Johannes Paulus Lotsy (April 11, 1867 – November 17, 1931) was a Dutch botanist, specializing in evolution and heredity. Lotsy was born in Dordrecht and died in Voorburg.

Career

After getting his PhD from Gottingen University he had a teaching positions at Johns Hopkins University (1891-1895) where he was director of the herbarium. From 1896 to 1900 he worked in Java.

He became director of the State Herbarium (Rijksherbarium) 1906-1909, then Secretary of the Hollandsche Maatschappij van Wetenschappen.

He founded the Association internationale des Botanistes and was editor of the Botanisches Centralblatt. He proposed a system of plant classification, based on phylogenetics.

Expeditions

India (1895-1900), the United States (1922), Australia and New Zealand (1925), South Africa (1926-27), and Egypt (1930). He also studied the flora of Italy and Switzerland.
