Kurt Gödel  (1906–1978), Mathematician, Philosopher.

Kurt Gödel was an Austrian-American logician, mathematician, and philosopher, born in the Austro-Hungarian city of Brno. He obtained what may be the most important mathematical result of the 20th century: his famous incompleteness theorems. These theorems established Gödel as one of the greatest logicians since Aristotle. When Germany annexed Austria, Gödel fled the Nazis to the safety of Princeton in the U.S., where he became a close friend of fellow exile Albert Einstein. Although Gödel was basically a mathematician, later his interest shifted towards philosophy. Gödel was awarded (with Julian Schwinger) the first Albert Einstein Award in 1951, and the National Medal of Science in 1974. Unfortunately, towards the end of life, he developed severe paranoia and fearing being poisoned, he starved himself to death.
