German philosopher Arthur Schopenhauer was born in Danzig (present-day Gdańsk) on February 22, 1788 and grew up in Hamburg. He was educated at the University of Göttingen and was a lecturer at Berlin University but settled in Frankfurt-in-Main where he lived for the rest of his life alone with his poodles. His most famous work, The World as Will and Representation, influenced many later thinkers, including Nietsche and Wittgenstein. (By John Osborne)
