Line 1:

Iss it really true that most mathematicians believe that the diagonal proof was Cantor's first proof of uncountability? I'm no mathematician, but even my topical interest in the matter turned up that fact long before this article was created. Is the misconception really that prevalent? -- [[User:Cyan|Cyan]] 20:51, 3 Nov 2003 (UTC)

I haven't carefully polled mathematicians to ascertain this, but I keep finding it asserted in print, and I've spoken with a number of intelligent mathematicians who were under that impression. [[User:Michael Hardy|Michael Hardy]] 19:53, 4 Nov 2003 (UTC)

Line 7 ⟶ 8:

:I've looked up Cantor's 1874 paper in ''Journal für die Reine und Angewandta Mathematik'', and the argument given in that article is indeed the one given here. See also Joseph Dauben's book about Cantor. This was indeed his first proof of this result. [[User:Michael Hardy|Michael Hardy]] 22:17, 12 Jan 2004 (UTC)

Was it really in 1877 that Cantor discovered the diagonal method, or was it later? I cannot find any proof for this. -- [[User:Zwaardmeester]] 19:52, 15 Jan 2006 (GMT+1)

'''This "proof" is logically flawed'''
