Aziz Nesin (pronounced [ˈaziz ˈne.sin ]; born Mehmet Nusret, 20 December 1915 – 6 July 1995) was a Turkish writer, humorist and the author of more than 100 books. Born in a time when Turks did not have official surnames, he had to adopt one after the Surname Law of 1934 was passed. Although his family carried the epithet "Topalosmanoğlu", after an ancestor named "Topal Osman", he chose the surname "Nesin".
