On Wikipedia the following statement is made without reference:

Wikipedia to the rescue!

FJ Dyson and A Lenard: Stability of Matter, Parts I and II (J. Math. Phys., 8, 423-434 (1967); J. Math. Phys., 9, 698-711 (1968) ); FJ Dyson: Ground-State Energy of a Finite System of Charged Particles (J.Math.Phys. 8, 1538-1545 (1967) )

I found the reference in ref 6 of

Thanks John. I should've browsed around a bit more on Wikipedia myself. I think I'll add these references from the Pauli exclusion principle page to the electron degeneracy pressure page. – Cameron Smith May 17 '12 at 20:52
