Georges-Henri Lemaitre was born in Charleroi, Belgium on 17 July 1894. Lemaitre studied humanities at a Jesuit school before entering the civil engineering school of the Catholic University of Leuven at the age of 17. Fred Hoyle is credited with coining the term Big Bang during a 1949 radio broadcast. It is popularly reported that Hoyle, who favored an alternative "steady state" cosmological model, at the time, proposed the term Big Bang as a striking image meant to highlight the difference between the two models. The consensus for modeling cosmology was agreed upon based on the work of four scientists: Alexander Friedmann, Georges Lemaître, Howard Percy Robertson, and Arthur Geoffrey Walker. It was developed independently by the named authors in the 1920s and 1930s. Occasionally referred to as the FLRW, FRW, FL, or RW (e.g., a complete or partial combination of their last initials) Universe, it presents a metric used to explain Einstein's field equation of general relativity and thus became the foundation for the currently understood version of the standard 'Big Bang Theory'.
