Heinz Steinitz
Three sons were born to Heinz Steinitz and Dr. Ruth Steinitz. Each turned to sciences: Raphael Steinitz, an astrophysicist, is a Professor Emeritus at the Department of Physics, Ben-Gurion University of the Negev, Be’er Sheba; Gideon Steinitz, a senior geologist, was the former Head of the Geological Survey of Israel, Jerusalem; and Benjamin Steinitz, a plant scientist retired as a senior research scientist in the fields of plant physiology and horticulture at the Institute of Plant Sciences, Agricultural Research Organization, The Volcani Center, Rishon LeZion.
Wilhelm Steinitz
Although he had a strong sense of honour about repaying debts, Steinitz was poor at managing his finances: he let a competitor "poach" many of his clients in 1862–63, offered to play the 1886 world title match against Johannes Zukertort for free, and died in poverty in 1900, leaving his widow to survive by running a small shop.
