Career
During his training in cabinet making, he lost an arm. In 1923, he joined the Communist Party of Germany (KPD), he belonged to the KPD factory cell and the Revolutionary Trade Union Opposition (Revolutionäre Gewerkschafts-Opposition) at the Deutsche Werkstätten Hellerau. In 1930, he was finally rebuked as a Communist works councillor and barred from the woodworkers" association.
Before the labour court, he struggled to keep working at the Workshops.
Not long afterwards, however, he had set up his own cabinet-making workshop on Leipziger Straße in Dresden. He was also leader of the singing company of the United Climbing Companies, which later became the "Sächsischer Bergsteigerchor "Kurt Schlosser" Dresden" ("Kurt Schlosser Saxon Mountaineers" Choir, Dresden").
From 1933, Schlosser was active with other mountain climbers in illegal "border work". His cabinet-making workshop became a meeting place for resistance fighters who were struggling against the Nazi régime.
There arose a tight connection between German and Czechoslovakian working-class sportsmen.
Kurt Schlosser contributed to the civic singing club "Melomanie" and the "Meißner Hochland" section of the German Alpine Club (Deutscher Alpenverein). On 3 December 1943, Kurt Schlosser and other active antifascists were arrested. On 16 August 1944, Kurt Schlosser was beheaded in the courtyard of the Dresden State Court at Münchner Platz.
The Sächsischer Bergsteigerchor "Kurt Schlosser" Dresden has borne the murdered antifascist"s name since 1949.
