Mallinckrodt Pharmaceuticals

This would have been in the 1940s, early or late 30s.

where a Manhattan Projects guy came to St. Louis to Edward Mallinckrodt and was like, all of these other chemical company barons are too cowardly to refine uranium for this giant bomb we're trying to make.

And Mallinckrodt was like, I'll do it for sure.

And then they refined a bunch of uranium in downtown St. Louis in an old stove factory.
