August Landmesser (1910 – presumably killed February 1944) was a worker at the Blohm + Voss shipyard in Hamburg, Germany. He appeared in a photograph refusing to perform the Nazi salute at the launch of the naval training vessel Horst Wessel on 13 June 1936.
“He had been a Nazi Party member from 1931 to 1935, but after fathering children with a Jewish woman, he had been found guilty of “dishonoring the race” under Nazi racial laws and had come to oppose Hitler’s regime. In February 1944 he was drafted into a penal unit, the 999th Fort Infantry Battalion, where he was declared missing in action and presumably killed.”
