Ernest Julius Wilczynski
Ernest Julius Wilczynski (November 13, 1876 – September 14, 1932) was an American mathematician considered the founder of projective differential geometry.[1]
Born in Hamburg, Germany, Wilczynski's family emigrated to America and settled in Chicago, Illinois when he was very young. He attended public school in the US but went to college in Germany and received his PhD from the University of Berlin in 1897.[2] He taught at the University of California until 1907, the University of Illinois from 1907 to 1910, and the University of Chicago from 1910 until illness forced his absence from the classroom in 1923. His doctoral students include Archibald Henderson, Ernest Preston Lane, Pauline Sperry, Ellis Stouffer, and Charles Thompson Sullivan.

gollark: ... how?
gollark: Or maybe some the people concerned about this are just vaguely transphobic, who knows.
gollark: I assume it's mostly just because it's a more recent issue, and possibly because it's smaller in scope and easier to deal with one than the others.
gollark: That works as a fully general counterargument for literally every problem except the worst one(s) that exist at some time.
gollark: I'm not sure how "some subgroup may end up able to shift the balance of sports rather a lot" is the same problem as "there exist many stupid people in America".
