In the years between 1914 and 1933 numerous significant personalities in art, culture, politics, society and sport met in the photographic portraiture studio of Nini and Carry Hess. With their technical and aesthetic brilliance, the sisters were among the leading photographers in Germany of the time. In the 1920s their photographs essentially stamped the image of Woman. Their long collaboration with the Städtischen Bühnen Frankfurt (Frankfurt city theaters) resulted in the portraits of numerous actors, both in the roles they played and in their own person. These included Albert Bassermann (1867–1952), Elisabeth Bergner, Carl Ebert (1887–1980), Heinrich George (1893–1946), Paul Graetz (1890–1938), Gerda Müller (1895–1951), Leontine Sagan (1889–1974); the composers Paul Hindemith (1885–1963) and Leos Janacek (1854–1928), and the authors Thomas Mann (1875–1955), Fritz von Unruh (1885–1970) and Carl Zuckmayer (1896–1977).
