Apr 26, 2017 at 23:22 comment added Santropedro @Dave I almost have a example for what you ask, if you accept it so. Cantor–Bernstein-Shroder theorem was according to wikipedia first proved by dedekind, althought he didn't published it.
Apr 16, 2011 at 20:46 comment added Dave I was told this by an older algebra professor of mine. Here's a reference (although I'm not sure how authoritative mathpages really is, especially because it doesn't cite sources itself): mathpages.com/home/kmath640/kmath640.htm
Oct 13, 2010 at 21:07 comment added The Mathemagician Guys,I'm not sure,but I think Frobenius was the first to STATE the theorum in it's full generality,but he didn't succeed in giving a complete proof.That's why Arthur Cayley and Hamilton are given credit-they supplied the first general proof,improving on thier original proofs in low dimensions.I could be wrong about this,someone please chime in if you have the right answer and give a reference.
May 12, 2010 at 22:41 comment added Guntram What do you mean? That Frobenius was the first to prove it in full generality? Please supply a reference, as Cayley and Hamilton at least had proofs in dimension 2 and 3, if I recall correctly.
