This is a common claim which has been repeated enough times that one can find many sources claiming it to be true. However, this doesn't seem to be corroborated by accounts of the time or serious biographies. Indeed, Helen M. Walker, in her 1934 biography of De Moivre in Scripta Mathematica Volume II, Number 4, August 1934, (reproduced here freely on Google ...

Margaret Wiener was, by all accounts, a controlling, conservative prude—
and she despised McCulloch’s influence on her husband. McCulloch

Although this story is frequently repeated, if you think about it you will realise that it is highly implausible. Let us start off with him sleeping eight hours a night. We will see him sinking from a normal sleep pattern to oblivion in just 4 x 16 = 64 days, or just over two months. Is such a thing possible?
I make this answer tentatively since I cannot find the document, an autobiographical chapter by Lettvin I read some years ago which discussed among other things this situation. Lettvin had a whole book available online, but searching I can't find it.
Basically, Lettvin claimed that Pitts and McCulloch were not sufficiently sympathetic to socialism, so far ...
