Max Hodann
Max Julius Carl Alexander Hodann (30 August 1894 – 17 December 1946) was a German physician, eugenicist, sex educator and Marxist, "the best-known and most controversial medical sex educationalist in the Weimar Republic". He wrote for a working-class readership (e.g. ''Guy and Gal'', 1924) and for children (e.g. ''Where Children Come From'', 1926). After 1933, as a refugee from Nazi Germany, he lived predominantly in Norway and Sweden. Provided by Wikipedia
