Need to identify a physicist from a documentary on TV some years ago

[Tiger Blood]

I remember watching some documentary on TV some years ago and in it, they were mentioning how there was a physicist who was doing some research on radioactive elements in the laboratory, but because he was little bit crazy he believed that the fez hat he wore on his head would protect him from radiation. Fez hat, of course, didn't shield him and he died.

So can anyone identify this scientist? I tried searching on google but couldn't find anything.
