Jim wanted to get a little away from the usual "murdery" conversations we have on the show, so for this week's episode he brought us a very interesting case that has very much shaped many modern labor laws and movements in the United States. It's pretty well known that radium is an element that was discovered by scientist Madame Curie and her husband. It's also pretty well known that Curie was eventually killed by the poisonous effects of this discovery. But she was not the only one. Turns out, in the 1920s radium was all the rage! It was marketed as basically a cure all for anything and everything. In its usage in the making of wrist watches at the time, the girls who worked directly with the element day in and day out would eventually suffer dire consequences despite their initial enthusiasm for the work because it was such a high paying job.
