Born in 1924, in Milan, Italy. Instead of studying renaissance artists, he prowled around witches' cauldrons. He retained a taste for the peculiar. In his works he used a range of miscellaneous materials: belts, mirrors, wallpaper, bits of fabric. In this same way, witches brewed the simplest and most dubious materials in their cauldrons, creating a devil's potion. His witchcraft was a gauge of contemporary confusions. André Breton discerned something errant in Baj's face: wandering traces of images coming into being; anguish over the present and apprehension; a laugh of deliverance.—In 1952, with Sergio Dangelo, he published the manifesto "Il Primo Manifesto Della Pittura Nucleare". —Died in 2003.
