At the beginning of 1933, about 0.76 percent of the German population was Jewish, but more than 3.6 percent of German university students were Jewish, this number having steadily declined from over 9 percent in the 1880s.[5] After 30 July 1939, Jews were no longer permitted to attend German public schools at all, and the prior quota law was eliminated by a non-public regulation in January 1940.[6]p. 193
