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.
Alfred Stieglitz
In 1924, Stieglitz's divorce was finally approved by a judge, and within four months he and O'Keeffe married in a small, private ceremony at Marin's house. They went home without a reception or honeymoon. O'Keeffe said later that they married in order to help soothe the troubles of Stieglitz's daughter Kitty, who at that time was being treated in a sanatorium for depression and hallucinations. For the rest of their lives together, their relationship was, as biographer Benita Eisler characterized it, "a collusion ... a system of deals and trade-offs, tacitly agreed to and carried out, for the most part, without the exchange of a word. Preferring avoidance to confrontation on most issues, O'Keeffe was the principal agent of collusion in their union."
