(b Nancy, 15 Mar. 1912; d Paris, 1 Dec. 1948). French painter. His early work was often of visionary subjects, but from about 1933 he began to paint mainly from the model in the studio; he also did still lifes, views through windows, and from 1937 landscapes painted out of doors. Gruber's mature style was grave and melancholy, featuring long, drooping figures, and he is regarded as the founder of the ‘Misérabiliste’ strain in French painting, later particularly associated with Buffet.
