Trude Fleischmann was a renowned portrait photographer in Vienna whose rise to prominence coincided with that of Hanne Wassermann. Both women had studied photography at the “Lehr- und Versuchsanstalt für Photographie und Reproduktionsverfahren,” their time at the school overlapping for at least one year. The two were friends, with Hanne posing as a model for Trude, including at least one nude photo in the early 1920s. When Hanne opened her 'gymnastics' school, it was Trude who photographed her for publicity materials such as posters and cards. Similarly, Trude photographed Hanne (sometimes accompanied by other models) demonstrating the various stretches and poses associated with the fitness method she had developed.

This subseries consists of photographs by Trude, the majority of which depict Hanne's fitness programs (e.g. stretching, holding poses, and ring exercises). There are also portraits taken of Hanne and photos of Hanne apparently modeling clothes. While Hanne is the primary subject of these images, there are also portraits of two unidentified men, one of whom was Hanne's boyfriend. There is also a small quantity of textual materials associated with Trude such as a newspaper clipping featuring one of her photos, materials related to Hanne's lectures at her New York studio, and a single piece of correspondence to Hanne.
