Liddy Bacroff (19 August 1908 – 6 January 1943) was a performer and sex worker of Weimar Republic era, persecuted and killed by the Nazi regime during World War II.

Bacroff was imprisoned several times for "homosexual acts" under Paragraph 175 of the German Criminal Code and ultimately killed in the Mauthausen concentration camp.

[1] In 1924, at the age of 16, Bacroff was first sentenced to six weeks in prison by the district court of Ludwigshafen for an offense under Section 176 (3) of the Reich Criminal Code; later the penalty was waived.

[2] In 1936, Liddy Bacroff was prosecuted for the first time under Section 4 of Paragraph 175 a of the German Criminal Code, which was newly introduced by the Nazis and made "commercial indecency" a punishable offense, and was sentenced by the Hamburg Regional Court to two years in the Bremen-Oslebshausen penitentiary with 3 years of "forfeiture of honor" (loss of civil rights).

[2] After the prison release in January 1938, Liddy Bacroff tried to evade constant police surveillance by using forged registration papers - whereupon a wanted warrant was initiated.

The doctor classified Bacroff as "incurable transvestite" (who would continue to sell sexual services to men), which was tantamount to a death sentence.

[2] On 22 August 1938, Liddy Bacroff was sentenced by the Hamburg Regional Court to three years in Zuchthaus with subsequent preventive detention for "commercial unnatural indecency" as a "dangerous habitual criminal".
