13. Pauli described himself as being three-quarters Jewish in a letter to the director of the Institute for Advanced Study, Frank Aydelotte, quoted in the April 1995 issue of Physics Today (p. 86). See also http://www.ethbib.ethz.ch/exhibit/pauli/ausreise_e.html. According to the family-authorized biography of Pauli by Charles Enz, No Time to be Brief: A Scientific Biography of Wolfgang Pauli (Oxford, Oxford and New York, 2002, pp. 1-7), three of Pauli's four grandparents (all but his maternal grandmother) were Jewish. Specifically, Pauli's father, Wolfgang Pauli, Sr. (originally Wolf Pascheles, whose parents came from the prominent Jewish Pascheles and Utitz families of Prague), converted from Judaism to Roman Catholicism shortly before his marriage in 1899 to Bertha Camilla Schütz. Bertha Schütz was raised in her mother's Roman Catholic religion, but her father was the Jewish writer Friedrich Schütz (whose biography can be found on p. 469 of Vol. 5 of S. Wininger's Grosse Jüdische National-Biographie). Although Pauli was raised as a Roman Catholic, eventually he (and his parents) left the Church.
