Felix Weltsch

German speaking Jewish librarian, philosopher, author, editor, publisher and journalist

Felix Weltsch (6 October 1884, Prague – 9 November 1964, Jerusalem), was a German speaking Jewish librarian, philosopher, author, editor, publisher and journalist. A close friend of Max Brod, Ludwig Winder and Franz Kafka, he was one of the most important Zionists in Bohemia.

Born in Prague (then in Austria Hungary), Weltsch studied Law and Philosophy at the Charles University. He lived and worked in Prague until 15 March 1939, and left the city with Max Brod and his family on the last train out of Czechoslovakia. In what at his arrival was Palestine and later the state of Israel, he worked as a librarian in Jerusalem until his death in 1964. He had one daughter, Ruth Weltsch (1920–1991), with his wife Irma Herz (1892–1969). They married in August 1914. The publisher, journalist and Zionist Robert Weltsch was Felix Weltsch's cousin, and the Prague born concert pianist Alice Herz Sommer, who performed in and survived Theresienstadt at her death the world's oldest Holocaust survivor, was his sister in law. His grandson, Eli Gorenstein is an actor, cellist and among Israel's leading voice dubbers.

Weltsch's works deal with the subjects of Ethics, Politics and Philosophy. For his ethical and political publications he received the Ruppin Prize from the city of Haifa in 1952. His most important work was the Jewish Zionist weekly paper Selbstwehr (self defense), which he led from 1919 until 1938. With this work and hundreds of articles he became one of the most important personalities in Jewish life next to Martin Buber, Chaim Weizmann and Hugo Bergmann, his early school friend.
