A. Edward Nussbaum (Rheydt, Mönchengladbach, 1925 – St. Louis, Missouri, 31 October 2009) was a theoretical mathematician and professor of mathematics at Washington University in St. Louis for nearly 40 years. He worked with others in 20th-century theoretical physics and mathematics such as J. Robert Oppenheimer and John von Neumann, and was acquainted with Albert Einstein. ==Early years== Nussbaum was born to a Jewish family in Rheydt, a borough of the German city Mönchengladbach in northwestern Germany, in 1925. The youngest of three children, he was a Holocaust survivor and was orphaned after the Nazi takeover of Germany.〔() Riley, M, ''Nussbaum was Shoah survivor, accomplished mathematician'' Saint Louis Jewish Light, retrieved November 8, 2009〕 Both his father, Karl Nussbaum, a wounded veteran of World War I during which he had been awarded the Iron Cross, and his mother, Franziska, died at Auschwitz. His brother, Erwin Nussbaum, was also captured and killed. Nussbaum and his sister, Lieselotte, were separated and sent on a Kindertransport to Belgium in 1939.〔 When Belgium was invaded by Germany, Nussbaum escaped to southern France, then under the Vichy regime. He lived there at an orphanage known as Château de la Hille. He began his teaching career there, while still a teenager, teaching mathematics to the younger children.〔 After being captured twice, and jailed once by the Nazis, he escaped on foot to Switzerland, where he attended the University of Zurich,〔() ''WUSTL flag at half-staff in honor of A. Edward Nussbaum'', retrieved November 8, 2009〕 studying both mathematics and physics. In 1947, he was sponsored by relatives in New Jersey to emigrate to the United States.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「A. Edward Nussbaum」の詳細全文を読む スポンサード リンク
