Before Burial
Otto's grave
In the Matzleinsdorf Protestant Cemetery (Vienna), with the inscription composed by his father.
"This stone marks the resting place of a young man whose spirit found no peace in this world. When he had delivered the message of his soul, he could no longer remain among the living. He betook himself to the place of death of one of the greatest of all men, the Schwarzspanierhaus in Vienna, and there destroyed his mortal body."
