Otto Weininger

Otto Weininger (; 3 April 1880 – 4 October 1903) was an Austrian philosopher who in 1903 published the book ''Geschlecht und Charakter'' (''Sex and Character''), which gained popularity after his suicide at the age of 23. Weininger had a strong influence on Ludwig Wittgenstein, August Strindberg, and, via his lesser-known work ''Über die letzten Dinge'', on James Joyce. Provided by Wikipedia
