The history of working women in Pittsburgh
Which bring up one of the most remarkable quotes I have ever found and use whenever the topic comes up:
(Pittsburgh) will, however, slowly decline unless new industries employing women and those engaged in the production of consumer goods are attracted to the area.
Which is from a report witten by a place called the Econometric Institute based News York City and titled: "Long Range Outlook for the Pittsburgh Industrial Area", stamped February 12, 1947 and was for the Allegheny Conference and the Pittsburgh Chamber of Commerce.
actually, I will say that again: 1947.
