In 1929, Walter Peterhans began teaching photography at the Bauhaus, and Stern joined him there the following year. Both Stern and Auerbach had previously studied with Peterhans. He taught his students to “see photographically,” as Stern put it, by anticipating the desired framing and lighting conditions of the composition before using the camera. ringl + pit’s photographic studies of silks and linens absorbed the lessons of their teacher and attracted the attention of advertising clients such as Maratti, a manufacturer of knitting machines for artificial silks. Several of their fabric studies, including Maratti. Artificial Silk (Maratti. Kunstseide), appeared in the 1931 issue of Gebrauchsgraphik, an international advertising trade magazine. Stern’s personal interest in fabric stemmed from her family’s textile business.
