Ernst Rodenwaldt

[1] He received a doctorate from the Friedrichs University, Halle in 1904 and conducted research on tropical nematode parasites and worked in Hamburg before being posted to German Togo in 1910.

Here he examined tropical infectious diseases and discovered a connection between the closing and opening of the Anecho lagoon and malaria outbreaks.

In 1915 he became a staff physician with the army and worked on malaria, typhus and cholera in Turkey and Asia Minor during World War I.

The washoff from the deforested hills led to the formation of new channels and the creation of stagnant pools where the mosquito larvae bred among the roots of Pistia stratiotes.

In 1934, he attended the conference of the International Federation of Eugenic Organizations held in Zurich along with Ernst Rüdin and Lothar Tirala [de].

In early 1946, at the insistence of his English colleagues, he was released to Germany, where he learned that he had already been dismissed from his position as a professor of hygiene by the American military government at the end of 1945 due to his involvement with the National Socialists.

[6] He made use of his publication on anthropological studies in Java on the Mestizos of Kisar to support the idea that he appreciated mixed race people.
