Arthur Ruppin

Arthur Ruppin was a German Zionist and one of the founders of the city of Tel Aviv. Appointed director of Berlin's Bureau for Jewish Statistics in 1904, he moved to Palestine in 1907, and from 1908 was the director of the Palestine Office of the Zionist Organization in Jaffa, organizing Zionist immigration to Palestine. In 1926, Ruppin joined the faculty of the Hebrew University of Jerusalem and founded the Department for the Sociology of the Jews. Described posthumously as the "founder of German-Jewish demography" and "father of Israeli sociology", his best-known sociological work was The Jews in the Modern World (1934). He was also a proponent of pseudoscientific race theory.
