Robert Oelbermann

In 1919 Robert and his brother Karl founded the Nerother Bund youth group in the Cologne region. Like other German youth groups, it aimed to bring youth closer to nature through camping and hiking. Homosexual relationships sometimes developed from the intense adolescent male camaraderie, and the Nerother Bund accepted these friendships, as did a number of German youth groups at the time.

1933-39: Soon after the Nazis took power in 1933, they dissolved all independent youth groups and urged the members to join the Hitler Youth movement. Robert refused and secretly continued his connection with the Nerother Bund. In 1936 he was convicted under the Nazi-revised criminal code's paragraph 175 which outlawed homosexuality. Robert was imprisoned with 13 other members of the Nerother Bund.

1940-41: Robert was one of more than 50,000 men sentenced under paragraph 175 during the Nazi regime. By 1941 he had been transferred to the Dachau concentration camp. Like many "175ers" in the camps, Robert was required to wear an identifying pink triangle. The "175ers" were commonly segregated in separate barracks, subjected to particularly harsh treatment, and often ostracized by other prisoner groups.

Forty-four-year-old Robert died at Dachau in 1941. Details of his death are unknown.
