I got 2. I am relieved. I sometimes think I spend too much time with science gossip instead of science, but glad to see not that much after all.
2 I did think maybe Beethoven, but I didn't know he had a brother, whereas Bernoulli was famous for having them. So were his brothers.
3 I had heard the story, so it was either Hardy or Littlewood. Either might have done this but Hardy was the type who might have written it up.
4 First time I had heard her called Elise, usually Lise. I didn't think 'cosmic physics' her thing so put one of those I had never heard of.
5 Put Barnard, could have been and only name I knew.
6 Didn't think any of them life and soul of parties, but Maxwell at least somewhat known for humour so put him.
7 Too old-fashioned sounding for Wiles, Hamilton never went to school, resembles another story about Gauss but I thought his teacher sadistic, would accept a right answer but not a cheeky one, put Kroneker
8 Got that right, Erdos and Perelman not public lecturing types, Neumann yes, know nothing of Hausdorff
9 Could have been either Klein or Poincaré, know nothing of other two
10 Toss-up Pauli and Bohr, both cussed types but Pauli more witty Bohr mar long drawn-out like this story so I should have put him.
11 That's enough gossip.
