Issachar Ber RYBACK
1897–1935, Ukraine/Russia

Born in Elizavetagrad in the Ukraine, Ryback studied at the Academy in Kiev. He emigrated to Berlin in 1921, and then on to Paris in 1926, where he was immediately successful. Wildenstein organized a big retrospective exhibition for him in 1935, but Ryback died suddenly just before the opening.
