Leuven, Where the Big Bang Theory was Born

Born in Charleroi on July 17, 1894, Georges Lemaître was an astronomer, cosmologist and professor at the KU Leuven university. He died in Leuven on June 20, 1966.  Georges Lemaître proposed what we know today as the prevailing Big Bang model of cosmology.

He was appointed lecturer at the KU Leuven in 1925. Then, he began to work on the subject that will make him internationally known and that will appear in 1927 in the Annals of the Société Scientifique de Bruxelles under the title "A homogeneous universe of constant mass and increasing radius accounting for the radial velocity of extragalactic nebulae". He received the diploma of Doctor of Philosophy and was subsequently appointed professor at the university. 

At the end of his life, he devotes himself more and more to numerical computation. He is in fact a calculator, algebraist and remarkable arithmetician.

“was interested in truth from the point of view of salvation just as much as in truth from the point of view of scientific certainty. It appeared to me that there were two paths to truth, and I decided to follow both of them.”
― Georges Lemaître
