Alferov's father, Ivan Karpovich Alferov, was most likely not Jewish.

10. Several visitors have confused Valentin Fabrikant with Valery Fabrikant, a Russian emigre professor convicted of multiple murders in Canada in the 1990s. Valentin Fabrikant developed the concept of the laser in the 1930s and 1940s. He was the first scientist to seriously analyze the process of light amplification by stimulated emission. Working in the Soviet Union, he developed techniques for producing population inversions, including the basic collisional technique used in many gas lasers, including the HeNe laser. In a 1951 patent, he further proposed optical pumping techniques and the use optical cavities.
11. See The Encyclopedia of Russian Jewry, Biographies A-I, edited by Herman Branover (Jason Aronson, Northvale, NJ, 1998, pp. 351-352). Frank's father was Jewish and his mother non-Jewish.
12. Friedmann's paternal grandfather was a Jewish cantonist. These were Jewish children conscripted into Russian military institutions, where they received military training and were placed under intense pressure to convert. Upon reaching the age of eighteen, they were then forced to serve in the Czarist army for another twenty-five years. The degree of Friedmann's Jewish ancestry is unclear, but he was probably no more than one-half Jewish. See Alexander A. Friedmann: the Man who Made the Universe Expand, by E. A. Tropp, V. Ya. Frenkel, and A. D. Chernin (Cambridge University Press, Cambridge and New York, 1993, Chapter 1). See also http://www.jewishgen.org/Belarus/rje_f.htm, which contains entries for both Friedmann and his father (both names spelled "Aleksandr Aleksandrovich Fridman").

14. Jewish father, non-Jewish mother. Jed Buchwald's biography of Heinrich Hertz, The Creation of Scientific Effects: Heinrich Hertz and the Discovery of Electric Waves (University of Chicago Press, Chicago, 1994, p. 45), conveys the misimpression that Hertz's paternal grandmother was not of Jewish origin. She was, in fact, born Betty Oppenheim and was the daughter of the prominent Jewish banker Salomon Oppenheim and his wife, whose maiden name was Levy. Hertz's father, Gustav Ferdinand Hertz (originally David Gustav Hertz), and both of Hertz's paternal grandparents, Heinrich David Hertz (originally Hertz Hertz) and Betty Oppenheim, all converted to Christianity. (See genealogical chart on p. 46 of Buchwald's biography and http://www.rrz.uni-hamburg.de/rz3a035/bundesstrasse1.html.)

21. 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.
