Chełmno extermination camp
Gustav Laabs (20 December 1902 – 12 March 1980) was a German SS commander during the Nazi era. During the Second World War, he worked as a gas van operator at the Chełmno extermination camp in Wartheland. As an operator of a gas van, Laabs was directly involved in the genocidal extermination of over 100,000 men, women and children, most of whom were Jewish. In November 1963, he was tried and convicted for crimes against humanity, and sentenced to 15 years (subsequently reduced to 13 years) by a regional court in Landgericht Bonn, Germany.
