Oskar and Otto Marmorek were two architects who, although related, never met but had a great deal in common. The Marmorek family was an assimilated Jewish family that included intellectuals, doctors and artists. They came from the region of Galicia, which was part of the Austro-Hungarian Empire in the 19th century and is now divided between Poland and Ukraine. Galicia was a multinational region of which the Jewish population was an important part.
