Leo Szilard (/ ˈ s ɪ l ɑːr d /; Hungarian: Szilárd Leó [ˈsilaːrd ˈlɛoː]; born Leó Spitz; February 11, 1898 – May 30, 1964) was a Hungarian-born physicist, biologist and inventor who made numerous important discoveries in nuclear physics and the biological sciences.

Leo Szilard was a Hungarian-born American physicist who helped conduct the first sustained nuclear chain reaction and was instrumental in initiating the Manhattan Project for the development of the atomic bomb.

Szilard was the chief physicist at the Chicago Metallurgical Laboratory from February 1942 to July 1946. He worked for Arthur H. Compton, the head of the Met Lab. Szilard helped build Chicago Pile-1, the first neutronic reactor to achieve a self-sustaining nuclear chain reaction.

Leo Szilard (1898-1964) was a Hungarian-born American physicist and inventor who played a key role in the development of the atomic bomb. Though he vocally opposed using the bomb in war, Szilard felt it was important to perfect the super-weapon before Nazi Germany.

Drafted into the Austro-Hungarian Army during the First World War, Szilard after the war went to Berlin and resumed his studies, initially in electrical engineering but then in physics at the University of Berlin, where he first met Albert Einstein and earned his Ph.D. in 1922.

2023年1月24日 · Born 125 years ago, the Hungarian–American physicist Leo Szilard is best remembered for being the first scientist to call for atomic bombs to be developed – before later demanding they be stopped.

Born Leo Spitz in Budapest, Hungary in 1898, Szilard received his PhD in Physics at the University of Berlin in 1922, becoming close friends with Albert Einstein during this time. In 1933, during the rise of Nazi Germany, Szilard moved to England to study nuclear chain reactions.
