Gerd Ziegler

Gerd Katter (14 March 1910 – 1995) was a German apprentice carpenter, insurance agent and patient of the notable German physician and sexologist, Magnus Hirschfeld. Katter is largely discussed in the context of his gender identity and status as a patient of Magnus Hirschfeld. Though he was assigned female at birth, Katter lived as a man, changing his name, pronouns and physical form to align with his sense of gender.
