Radium Girls: In this case, it's not the death that is a crowning moment, but the aftermath of said death. A woman from the 1920s named Wendy died by covering herself with glow-in-the-dark, radioactive paint (using it as body paint for her lover during sex), and contracted bone cancer. She got the idea because the company she worked for knew about the dangerous effects of radium, yet used it in their paint anyway, and in fact encouraged the female workers to keep their paintbrushes sharp by licking them, and thus consuming dangerous radioactive material. After the woman's death, her co-workers filed one of the first successful workers' rights lawsuits, won, and according to the narration, "increased safety standards across America." The Other Wiki confirms this as the truth; it was the first successful lawsuit of its kind in the United States.
