Today is Volkstrauertag in Germany, and a special service was held at Peterskirche, the University of Heidelberg church, to commemorate all of the professors who were forced out of their positionsby the Third Reich and suffered great hardships including being sent to concentration camps. A rough translation from various websites is this, with a more detailed description here, in Deutsch.
This Memorial Day is a state memorial in Germany and is one of the "silent days". Since 1952 it is celebrated two Sundays before the first day of Advent, and commemorates the war dead and victims of the tyranny of all nations.
The primary memorial ceremony is held each Memorial Day at the German Bundestag. Generally there is a speech by the President in the presence of the Chancellor, the Cabinet and the diplomatic corps, with musical performances including playing the national anthem and the song I Had A Comrade.
After the service which included reading the biographies of several of the professors, the university leadership led a recession outside to the courtyard shown above where two wreathes were placed in remembrance of both the professors who were purged as well as students who were also expelled.
In Silence, Remember
