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.
Adolf Hitler and Stefanie Rabatsch
According to Kubizek, Hitler never spoke to Stefanie, always saying he would do so "tomorrow". 
Kubizek wrote that Hitler loathed those who flirted with her, especially the military officers, whom he called "conceited blockheads"; he came to feel an "uncompromising enmity towards the officer class as a whole, and everything military in general. It annoyed him that Stefanie mixed with such idlers who, he insisted, wore corsets and used scent". 
Hitler insisted that Kubizek stalk Stefanie and delivered daily reports on her activity while he was away visiting his mother or family. In one report, Kubizek wrote that Stefanie loved to dance and had taken lessons. Hitler disliked dancing and reportedly replied, "Stefanie only dances because she is forced to by society on which she unfortunately depends on. Once Stefanie is my wife, she won't have the slightest desire to dance!" In June 1906, Stefanie allegedly gave Hitler a smile and a flower from her bouquet as she was passing him in her carriage. Kubizek later described the scene:"Never again did I see Adolf as happy as he was at that moment. When the carriage had passed he dragged me aside and with emotion he gazed at the flower, this visible pledge of her love. I can still hear his voice, trembling with excitement, 'She loves me!' "After Hitler's mother died of breast cancer in 1907, the funeral procession went through Urfahr to Leonding. Kubizek remarks that Hitler said he had seen Stefanie at the funeral procession, which gave him some consolation. Kubizek claims that "Stefanie had no idea how deeply Adolf was in love with her; she regarded him as a somewhat shy, but nevertheless remarkably tenacious and faithful, admirer. When she responded with a smile to his inquiring glance, he was happy and his mood became unlike anything I had ever observed in him. But when Stefanie, as happened just as often, coldly ignored his gaze, he was crushed and ready to destroy himself and the whole world." 
Kubizek claims that Hitler finally stated he planned to kidnap Stefanie and kill both her and himself by jumping off a bridge into the Danube. 
Instead he moved to Vienna, where, according to Kubizek, an idealised image of Stefanie became his moral touchstone.
Stefanie stated in later interviews that she was unaware of Hitler at the time, but that she had received an anonymous love letter asking her to wait for him to graduate and then to marry him, which she only realised after being questioned about him, must have been from Hitler. She recalled: "I once received a letter from someone who said they were to attend the Academy of Arts, and that I should wait for him; he could come back and marry me! I had no idea who the letter might have been from or who I should have send it to."
