Ludwig Wittgenstein
Ludwig Josef Johann Wittgenstein ( in German) (April 26, 1889 – April 29, 1951) was an Austrian philosopher. He worked mainly in the basics of logic, the philosophy of mathematics, the philosophy of mind, and the philosophy of language. He is regarded as one of the most important philosophers of the twentieth century.
Before his death at the age of 62, the only book Wittgenstein had published was the "Tractatus Logico-Philosophicus". His second book "Philosophical Investigations" was published shortly after he died. Both of these works are regarded as very important for analytic philosophy.
Ludwig Wittgenstein was born in Vienna on 26 April 1889, to Karl and Leopoldine Wittgenstein. He was the youngest of eight children and was born into one of the most prominent and wealthy families in the Austro-Hungarian empire. His father's parents, Hermann Christian and Fanny Wittgenstein, were born into Jewish families but later converted to Protestantism, and after they moved from Saxony to Vienna in the 1850s, assimilated themselves into the Viennese Protestant professional classes. Ludwig's father, Karl Wittgenstein, became an industrialist and went on to make a fortune in iron and steel. Ludwig's mother Leopoldine, born Kalmus, was an aunt of the Nobel Prize laureate Friedrich von Hayek. Despite Karl's Protestantism, and the fact that Leopoldine's father was Jewish, the Wittgenstein children were baptized as Roman Catholics — the faith of their maternal grandmother — and Ludwig was given a Roman Catholic burial upon his death. Wittgenstein was homosexual.
Wittgenstein began studying mechanical engineering. During his research he became interested in the foundations of mathematics, particularly after reading Bertrand Russell's "Principles of Mathematics" and Gottlob Frege's "Grundgesetze". In 1911 Wittgenstein visited Frege and Russell and discussed philosophy with them at great length. He made a great impression on Russell and started to work on the foundations of logic and mathematical logic. Russell saw Wittgenstein as a successor who would carry on his work.
