Heinz Steinitz
Heinz Steinitz was born in Breslau, Germany (now Wroclaw, Poland) on April 26, 1909, to Walter Steinitz (1882-1963), a cardiologist and zoologist, and Marta Schindler Steinitz (1885-1926). He grew up in Breslau and was greatly inspired by his father to study science and to be an active Zionist. He studied medicine from 1927-1933 in the universities of Breslau, Freiburg and Berlin. Although he passed the Medical Board examination in 1933, and would have started work in a hospital in Berlin and in the Jewish hospital in Breslau, he was prohibited from practicing by the Nazi regime which came to power that same year. Together with his wife Ruth Aber Steinitz (1907-1995), a medical student as well, he left Germany in 1933 and immigrated to Palestine.
Erwin Schrödinger
On 6 April 1920, Schrödinger married Annemarie (Anny) Bertel. Schrödinger suffered from tuberculosis and several times in the 1920s stayed at a sanatorium in Arosa. It was there that he formulated his wave equation. As has been noted above, Schrödinger had an unconventional personal life. When he migrated to Ireland in 1938, he obtained visas for himself, his wife and also another woman, Mrs. Hilde March. March was the wife of an Austrian colleague and Schrödinger had fathered a daughter with her in 1934. Schrödinger wrote personally to the Taoiseach, Éamon de Valera, to obtain the visa for Mrs. March. In October 1939 the "ménage à trois" duly took up residence in Dublin. Schrödinger fathered two further daughters by two different women during his time in Ireland.
