Welcome to the world of physicist, molecular biologist, and
“scientist of conscience” Leo Szilard (1898-1964).
Szilard conceived the nuclear chain reaction in 1933,
and spent the rest of his life trying to protect the world from nuclear weapons.
Szilard’s other inventions
included the linear accelerator, cyclotron, and electron
In his 1929 paper on Maxwell’s Demon, Szilard identified
the unit or “bit” of information. The rise of the Information Age
shows the importance of his long-unappreciated idea.
Szilard’s name can be pronounced in different ways. In
Hungary, it is pronounced SEE-lahrd. English speakers usually pronounce it as ZIL-ahrd or zuh-LAHRD.
