Lucien Godeaux (1887–1975) was a prolific Belgian mathematician.
His total of more than 1000 papers and books, 669 of which are found in Mathematical Reviews, made him one of the most published mathematicians.
From Liège, he was attracted to the work of the Italian school of algebraic geometry by the work of one of its masters, Federigo Enriques.
The Godeaux surface is a construction of a special type, which has subsequently been much studied.
Since 2007, the Belgian Mathematical Society (BMS) is organising a "Godeaux lecture" in his memory.
