My mom was a secretary at GM in Flint, Michigan, in the '60s before having me. Of course, once she got pregnant, she had to resign—that's how it was done in those days.
She actually had a lot of responsibilities, including arranging for the delivery of certain models all around the world when they were bought by individuals.
In the above notes from a speech her boss gave, check out how he introduces the women in his office:
“...some extremely fine additions to the Opel line. Here's one of our exciting new models. Linda Rettenmund [my mom] is the stenographer with primary responsibility for foreign delivery details. And...
“...Ruth Ann Bissonette is the new opel typist-clerk and will handle the receipt of orders, releasing details, etc.
“These additions are in keeping with the new trend in Opel: Sharp styling, lovely trim, to say nothing of options.”
