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.
Lyndon LaRouche
In 1977 LaRouche married his current wife, Helga Zepp-LaRouche, who is German and 27 years younger than he. Her 1984 book, "The Hitler Book" argues that "We need a movement that can finally free Germany from the control of the Versailles and Yalta treaties, thanks to which we have staggered from one catastrophe to another for an entire century." 
Helga founded the Schiller Institute, which has been accused of antisemitism by the "Berliner Zeitung" and Political Research Associates, a non-profit research group that studies right wing, white supremacist, and militia groups.
