Monsignor Georges Henri Joseph Édouard Lemaître ( lemaitre.ogg (help-info) 17 July 1894 - 20 June 1966) was a Belgian priest, astronomer and professor of physics at the Catholic University of Louvain. He was the first person to propose the theory of the expansion of the Universe, widely misattributed to Edwin Hubble. He was also the first to derive what is now known as the Hubble's law and made the first estimation of what is now called the Hubble constant which he published in 1927, two years before Hubble's article . Lemaître also proposed what became known as the Big Bang theory of the origin of the Universe, which he called his 'hypothesis of the primeval atom'. He sometimes used the title Abbé or Monseigneur.
