Willi Graf was a Roman Catholic member of the White Rose resistance group in Nazi Germany. Willi Graf's family moved to Saarbrücken in 1922, where his father ran a wine wholesaler, and was the manager of the Johannishof, the second largest banquet hall in Saarbrücken. Graf went to school at the Ludwigsgymnasium. It was not long before he joined, at the age of eleven, the Bund Neudeutschland, a Catholic youth movement for young men in schools of higher learning, which was banned after Hitler and the Nazis came to power in 1933. In 1934, Graf joined the Grauer Orden, another Catholic movement which became known for its anti-Nazi rhetoric. It, too, was banned and for this reason, it formed many splinter youth groups. Graf showed conviction in his beliefs from a young age. Although compulsory at the time, he refused to associate with the Hitler Youth. While other future members of the White Rose initially embraced the Hitler Youth, Graf never did so. Moreover, in his address book he crossed out the names of friends who had joined the Hitler Youth. In 1935, at the age of 17, Graf and a few friends marched in an annual May Day parade. The parade was dominated by swastikas, brown-shirted Hitler Youth troops marching in formation, and "Sieg Heils." However, Graf and his friends marched under their tattered school flag, making great effort to stand out from their peers. They did not don any swastikas, or participate in any of the "Sieg Heil" salutes. After his Abitur, the German equivalent of Baccalauréat, in 1937, Willi Graf did his six-month Reichsarbeitsdienst and afterwards began his medical studies. In 1938, he was arrested along with other members of the Grauer Orden and charged by a court in Mannheim with illegal youth league activities–the Bünde having been banned–in relation with his unlawful field trips, camping excursions and other meetings with the Grauer Orden. The charges were later dismissed as part of a general amnesty declared to celebrate the Anschluss. The detention had lasted three weeks. His time in jail did not weaken his decision to participate in anti-Nazi activities or organizations.
