Queer history fact: Frieda Belinfante, the first woman in Europe to be artistic director and conductor of an ongoing professional orchestral ensemble, joined the CKC resistance group around the beginning of WW2. CKC included other queer members, such as Willem Arondeus. In her interview with the Holocaust Museum, she claims that she was the one who pointed out that if they were going to forge documents, they also had to destroy the originals so no one caught on. This led to the destruction of the Amsterdam public registry on March 27, 1943.
As a woman, Belinfante herself was not allowed to go on that mission, so she only knew that her fellow group members were captured when her right-hand man didn’t show up to the meeting spot. She immediately abandoned her home and disguised herself as a man. It was only later that she learned the others of the group had been executed.
