> they were nearly exclusively occupying the industry That was true when computing was running tabulating machines. That led to the early ENIAC programmers (all 6 of them) being women since they had traditionally run the tabulating machines. However men had been programming before this (e.g., Zuse, others developing hardware and testing it). Once "computing" became what modern people think of as programming, men dominated, not because of sudden sex discrimination or exclusion in computing, but because the input pipeline of what a programmer did changed to people coming from academia instead. The first computer science degree in the world (Cambridge 1953) drew students of math and engineering. The first in the US (Purdue, 1962, first MS degrees 1964, first PhDs 1966) did the same. So it's likely as the field expanded women were not pushed out as much as more men joined in.
