Alfred Pringsheim
Alfred Pringsheim was a German mathematician and patron of the arts. He was born in Ohlau, Prussian Silesia and died in Zrich, Switzerland. One of many antisemitic pieces of Nazi legislation, the Namensnderungsverordnung which came into effectJanuary 1938, forced him to legally change his name into Alfred Israel Pringsheim at age 87.
In 1878 he married the Berlin actress Gertrude Hedwig Anna Dohm , whose mother was the famous Berlin advocate of womens rights Hedwig Dohm . They had five children Erik , Peter , Heinz and twins born in 1883, Klaus and Katharina, known as Katia. His firstborn son, Erik, was exiled to Argentina because of his dissolute life and gambling debts and died there at an early age. His sons Peter and Klaus followed him in pursuing academic careers, obtaining professorships in physics and musical composition. One musician in the family was enough, so his third son,Heinz, became an archaeologist with a doctorate in that field, but soon changed course, becoming a successful conductor and critic in Berlin and Munich. His daughter Katia was the first female in Munich to earn the qualifications for university admission and was one of the first active women students at Munich University. She later became the wife of the author and Nobel Prize winner Thomas Mann.
