Kurt Hiller (17 August 1885, Berlin – 1 October 1972, Hamburg) was a Jewish German essayist of high stylistic originality and a political (namely pacifist) journalist from a Jewish family. An openly gay communist he was deeply influenced by Immanuel Kant and Arthur Schopenhauer, despising the philosophy of G. W. F. Hegel, which made him quite unpopular with Marxists. Hiller was also an influential writer in the early German gay rights movement in the first two decades of the 20th century. In 1929, Hiller took over as chairman of the Scientific Humanitarian Committee from fellow gay activist Magnus Hirschfeld.
Hiller was arrested by the Gestapo in 1933 following the Nazi seizure of power and was severely beaten before his release in August 1933. He spent nine months in prisons and in the earliest concentration camps, being transferred to Columbia-Hauss, Brandenburg and Oranienburg concentration camp.
