Felix Luxenburg was a Jewish architect who started his own real-estate company in Berlin in 1922, but was banned from running it in 1937. At the end of 1939, he was drafted into forced labor at the Teves works in Berlin-Wittenau. From 1941, the “Jewish department” there was run by the anti-Nazi foreman Wilhelm Daene. Luxenburg was the only man in the department. Daene tried his best to protect the forced laborers. During the large-scale raid on February 27, 1943, Daene helped Felix Luxenburg to hide in a bathroom, and he escaped over the works fence at around midnight. He had to change his hiding places on several occasions. Felix Luxenburg stayed with Anna Fisch in Berlin-Johannisthal for about a year. He survived.
