Hermann Ungar (April 20, 1893 in Boskovice – October 28, 1929 in Prague) was a Moravian writer (in the German language) and an officer in Czechoslovakia's Ministry of Foreign Affairs. His novels were influenced by expressionism and psychoanalysis. He was praised as a great writer by Thomas Mann, who became a godfather to Ungar's son Tom (born Thomas Michael Ungar). According to an obituary of Tom (25 October 1923 – 29 May 2012), Ungar "wrote about sex and psychosis in a manner that shocked the establishment".
