 Ernst Freud established his practice in Berlin in 1920 where a large number of his clients were doctors.The majority of his commissions were for houses and consulting rooms and he worked in an Art Deco style but by 1930 had begun to work in a modern style showing the influence of Mies van der Rohe.Examples of this include a cigarette factory in Berlin and a house for Dr. Frank in Geltow near Potsdam.
