Richard Phillips Feynman (1918-1988) was a physicist with a long and distinguished career, from the Manhattan Project to quantum field theory to investigating the Challenger space-shuttle disaster. He shared the 1965 Nobel Prize in Physics for his work in Quantum Electrodynamics, the quantum-mechanical theory of the electromagnetic field.
In What Do You Care What Other People Think? (1988), Feynman described himself as "an avowed atheist" by his early youth. "I thought nature itself was so interesting that I didn't want it distorted (by miracle stories). And so I gradually came to disbelieve the whole religion."
