1) Once mainframe electronic computers started to be routinely manufactured computing jobs became engineering jobs which were primarily male. 2) When I was at Stanford and MIT in the 1970s, there was a debate whether Computer Science was a legitimate STEM topic and deserved a separate department (took MIT until 2018 to recognize such). Part of this was programming was considered a trade-school subject, feminine and secretarial, not unlike typing. 3) My first industrial science job I was assigned a (female) clerk who would keypunch my coding sheets, submit job decks and retrieve lineprinter output. The senior scientists considered it beneath their dignity to sully their hands with mundane programming tasks. I was considered an upstart for doing my programming personally and code rapidly outcode the senior staff.
