Steven Weinberg (born May 3, 1933)
According to Wikipedia, "Weinberg is an American physicist. He was awarded the 1979 Nobel Prize in Physics (with colleagues Abdus Salam and Sheldon Glashow) for combining electromagnetism and the weak force into the electroweak force."
His most famous quote on religion is:
"Religion is an insult to human dignity. Without it you would have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes religion."
