The Atlantic has a great collection of essays on gender and technology gathered in one place, Happy Ada Lovelace Day! A Collection of Essays on Gender and Tech From Your Friends at The Atlantic. The page of stories includes a scan of the 1951 internal memo that allowed IBM female employees to get married (that you see above.) It also includes a story about Etsy’s prioritizing diversity in hiring which led to a significant improvement in the ratio of female to male engineers.
All of this in honour of Ada Lovelace Day!
