20/06/1996 Belgian cosmologist Georges Lemaitre dies

Georges Lemaître, was a Belgian Catholic Priest, astronomer, professor of physics and inventor of the Big bang theory. When studying general relativity, he realized that if the universe was expanding, then the further we go in the past, the universe's contents must have been closer together. At some point in the distant past, all the matter in the universe was crushed into a single object, which he called the primeval super-atom.
