Heinz Steinitz
Three sons were born to Heinz Steinitz and Dr. Ruth Steinitz.

Otto Hintze
Hintze ceased publishing after the Nazi Party came to power and, in 1933, he was the only member to speak against Albert Einstein's expulsion from the Prussian Academy of Sciences. In 1938, Hintze himself resigned from the Academy, which he had been a member of since 1914. His wife, Hedwig Hintze (born: Hedwig Guggenheimer), who was Germany's first woman to receive a doctorate in History and the University of Berlin's (Friedrich Wilhelm University) first woman History professor, because of her Jewish roots and leftist sympathies soon lost her position as lecturer at the Friedrich Wilhelm University, and eventually had to flee to the Netherlands in 1939. Otto Hintze only survived this separation for a few months. In 1942, his wife committed suicide rather than undergo deportation to a death camp by the Nazis.
