There is a Wikipedia page with a List of inventors killed by their own inventions. I was hoping to find someone really famous on there. Marie Curie is the most famous name on the list, but since she didn't really invent radiation as such, I felt that was kind of cheating. I settled for the Titanic engineer, Thomas Andrews, since even if people don't know his name, he's easy to describe.

I was really hoping for something along the lines of Alexander Graham Bell having died during a tragic phone booth stuffing incident or something. The cosmic irony inventory on causes of death of famous inventors is critically low.
