G. Comba at Prescott. Guido Fubini (1879-1943) taught at the universities of Catania, Genoa and Turin. In 1938 he was invited to join the Institute for Advanced Study at Princeton. Fubini was a prolific and eclectic mathematician who made contributions in analysis, algebra, geometry and mathematical physics.
