Who formulated the hypothesis?
The following can be read in the beginning of the article: "It [the Knudsen hypothesis] was first proposed by Carl O. Nordling in 1953,[1][2] and later formulated by Alfred G. Knudson in 1971.[3]".

I read the paper by Nordling ([1]) and while it discusses the number of mutations required in the genome to develop cancer, it does not as far as I can tell at all relate to the two-hit hypothesis formulated by Knudsen which discusses that a hit (mutation) was required to each allele of the same gene (RB) to cause cancer. I would argue the statement in the Wikipedia article above quoted is false. I can however not access [2].
