Hermann Freiherr von Teschenberg (6 July 1866 – 6 November 1911) was an Austrian barrister, translator, and an LGBT rights activist.
He was discovered kissing a soldier in Prater park in Vienna, after which he fled to Italy in 1893-94, and later to England.
By his own account, he met Oscar Wilde and tried to mediate between the writer and the father of Lord Alfred Douglas, the Marquess of Queensberry.
In early 1898, he settled in Berlin, joining Magnus Hirschfeld, who had founded the Scientific-Humanitarian Committee.
He was also a transvestite and photographed several times wearing women's clothing for the Committee magazine.
