Giacomo Girolamo Casanova (Venice 2 April 1725 – Dux, now Duchcov, 4 June 1798) was an Italian adventurer and author from the Republic of Venice. His autobiography, Histoire de ma vie (Story of My Life), is regarded as one of the most authentic sources of the customs and norms of European social life during the 18th century. He has become so famous for his often complicated and elaborate affairs with women that his name is now synonymous with "womanizer". He associated with European royalty, popes and cardinals, along with luminaries such as Voltaire, Goethe and Mozart. He spent his last years in Bohemia as a librarian in Count Waldstein's household, where he also wrote the story of his life.
