The BMS "Godeaux lecture prize" is named in honor of prolific Belgian mathematician Lucien Godeaux. The prize is awarded every year, upon proposal from a BMS board member, to a prominent belgian or international mathematician who is invited to give a talk at a conference in Belgium.

These lectures honoring the memory of Lucien Godeaux are organized with the assets of the Belgian Center for Mathematical Studies which were transferred to the BMS after the dissolution of this Center. Lucien Godeaux (1887-1975) was one of the world's most prolific mathematicians (with more than 700 papers published) and took many initiatives to encourage young mathematicians to communicate their research. He was the founder of the Belgian Center for Mathematical Studies in 1949. The Godeaux lecture is aimed at a broad audience with interest in mathematics.
