Ulrich Graf
Shortly after the First World War, Graf became a member of the German Workers' Party (DAP). Later, the DAP was renamed the National Socialist German Workers' Party (NSDAP; Nazi Party) and taken over by Adolf Hitler. Founded in 1920, the "Sturmabteilung" (SA) was the first of many paramilitary protection squads that worked to protect Nazi officials. These storm troopers, outfitted in brown uniforms, were initially charged with the duty of keeping order at Nazi Party meetings. They soon expanded their role to include disruption of rival political party's functions. Graf was an early member of the SA. In 1921, he became member number 2882 of the Nazi Party.
Wolfgang Köhler
The Nazi party, led by Adolf Hitler, rose to power on January 30, 1933. The regime started practicing discriminatory policies against Jews, and dismissed any professors with a Jewish background from German universities. Max Planck, a well-known physicist, petitioned Hitler to stop the dismissal of Jewish professors, stressing their importance regarding scientific contributions. Hitler has been quoted as responding to Planck, "if the dismissal of Jewish scientists means the annihilation of contemporary German science, then we shall do without science for a few years".
