Since WW2, the members of the White Rose, and Hans and Sophie Scholl in particular, have been held up as heroes, and one member of the group was even sainted by the Orthodox church. Do we know what came of Jakub Schmied, the university maintenance man who turned in the students after he saw them throwing some pamphlets? It seems like he might have been pretty unpopular in post-war Germany.
Jakob Schmid was awarded 3000 Reichsmark and a promotion for his role in apprehending the White Rose. After the war, he was arrested in '45 by US troops, was freed after thirteen weeks of internment but lost his job and was subsequently put on trial in '46. There he was sentenced to five years in prison, was banned from holding public office and lost his rights on his pension.
During his time in jail he wrote two petitions for mercy, but to no avail. Nevertheless, after he was released from jail in '51, his rights on his pensions were restored, in line with the German practice of continuity to avoid unrest (because of which many low level functionaries and supporters of the Nazi party were allowed to keep living their life, keep their jobs etc. since they were considered too important to rebuild the country). Schmid died in '64.

He received around 3000 Reichmarks for informing on the white rose movement in 1943, after the war he was convicted during the denazification process and sentenced to 5 years in prison most of which he served, and had his pension removed. He pleaded clemency upon being convicted, claiming that he was uninterested in the content of the leaflet but simply doing his duty since there was a law which forbid the distribution of leaflets. This claim was not accepted very well by the courts but he was released somewhat early in 1951. His pension was restored to him upon his retirement. He died in 1964.
