John Moore did in fact publish his proof that simplicial groups are
Kan. It is stated as Theorem 3.4 in his paper Semi-Simplicial Complexes
And Postnikov Systems (page 242 of the book, Symposium International De
Topologia Algebraica, 1956 conference, book published in 1958). Moore
refers to the Seminaire Cartan, 1954-55, expose XVIII, where the proof
is given in full as Theorem 3 on page 18-04.

I'm sorry my previous email contained too much rubbish pasted from
Mathscinet.
Let me say that the review MR1173825 of the cubical case, by Andrew
Tonks, refers to *MR0087934 *Séminaire Henri Cartan de l'Ecole Normale
Supérieure, 1954/1955. Algèbres d'Eilenberg-MacLane et homotopie. *"*In
den Protokollen 18, 19, 21 betrachtet Moore Monoid-Komplexe."
But I don't have a copy of the seminar to check.

Mike,
I believe this theorem first appeared in Moore's
1956 Princeton notes "Seminar on algebraic homotopy theory".
Unfortunately I seem to have lost my copy of this, so
I can't really verify it, but I'm pretty sure.

Dear All,
In Curtis's survey article he gives Kan's paper: A combinatorial
description of homotopy groups, Ann. Math. 67(1958)288 - 312.
Actually I believe that the algorithm that Curtis gives does not work.
That in Peter May's book does.

The result first appeared in
J. C. Moore, Homotopie des complexes monoideaux, I, Seminaire Henri Cartan,
1954-55. See Theorem 3 on p. 18-04.
This is available on the web at
http://archive.numdam.org/article/SHC_1954-1955__7_2_A8_0.pdf
The result became somewhat more widely known as a result of
J. C. Moore, Seminar on algebraic homotopy theory, Mimeographed notes, Princeton
University, Princeton, N. J., 1956

The theorem is due to John Moore, but as far as I remember
he never published his proof. It appeared in mimeographed
notes entitled ``Seminar on algebraic homotopy theory'',
Princeton, 1956. The result is Theorem 17.1 in my 1967 book
``Simplicial objects in algebraic topology'', and the argument
there is based on Moore's notes (Moore was my adviser).
