Career
After the First World War, Landauer became a pacifist. In 1916, he fell ill with typhus and was subsequently transferred to a military prison in Heilbronn as a doctor. There he met and married Lins Kahn. After the war, he settled and ran a private practice in Frankfurt am Main c.1923. He became friends with Max Horkheimer. The Frankfurt Psychoanalytical Institute, co-founded by Landauer, cooperated with Horkheimer's Institute for Social Research, in whose rooms he had guest status. In 1933 both facilities were closed.
