Ellen (Rosenberg) Auerbach (May 20, 1906 – July 30, 2004) was a German-born American photographer who is best remembered for her innovative artwork for the ringl+pit studio in Berlin during the Weimar Republic.

[3] Rosenberg took no interest in the family business, so her parents allowed her to study, but provided little financial support or encouragement.

[5][6] In 1929 Rosenberg moved to Berlin to study photography with Walter Peterhans, who was a member of the Bauhaus design movement.

[6] Whilst Stern's specialty was in graphic design and the formal aspects of photography, Rosenberg provided the humorous and ironic touches to their representations of women in advertising and film.

They photographed friends and lovers they met through bohemian circles, including the dancer Claire Eckstein and the poet Marieluise Fleisser.

Heiterer Tag auf Rügen mixed elements of nature with images of friends from a visit to the island of Rugen.

Gretchen hat Ausgang was a short silent drama, which featured Stern as a clumsy maid, and her future husband Horacio Coppola as a handsome man who tries to seduce her at the local ice-cream parlour.

[3] When Hitler rose to power in 1933, Walter Auerbach, an activist in left wing political circles, warned them of the dangers ahead.

[3] Shortly after her arrival Rosenberg became the official photographer for the Women's International Zionist Organisation (WIZO), and made Tel Aviv, a 16 mm black and white film about the growing city.

[3] After Stern emigrated to Argentina in 1936, Rosenberg tried but failed to obtain a work and residency permit to run the London studio.

[7] In 1940 Ellen and Walter Auerbach moved to New York,[14] where she worked freelance for magazines, including Time, Life and Photo Technique.

[3] Between 1946 and 1949 Ellen Auerbach worked with Dr. Sybil Escalona, a child psychologist, at the Menninger psychiatric institute in Kansas.

[7] Auerbach's hometown organized a show in 1988 called Emigriert, and the Folkwang Museum in Essen mounted a comprehensive ringl+pit exhibition in 1993.

[3] In 1936 Walter Rosenberg secured a visa for Argentina and sailed there to live with Stern, who was then married to Horacio Coppola.
