== Poor Yorick! == 

 His non-Jewishness is given way too much weight, too early in the article. Propose to move the whole opening paragraph of Youth and studies, minus the first sentence, between 
 : Cantor's paternal grandparents... 
 and 
 :  ... rabbinical law 
 to a separate section at the end of the article, just before Notes, so that the beginning of the main text of the article (past lead) reads: 
 : Cantor was born in 1845 in St. Petersburg, Russia, and brought up in St. Petersburg. He [Cantor] was the eldest of six children. 

 That section at the end would also be a good place to put in the fascinating description of the bibliographical sources on Cantor, which may be the best thing that resulted from the discussion, in a normal font (presently, it is set in such a tiny font that it actually hurts one's eyes to read).
