Live Science notes that Stephen Glashow first came up with the notion of the subatomic cascade back in 1960 and that it’s been a matter of pure theory that whole time.Pretty sure they meant Sheldon Glashow, not that I'm pretending to have ever heard of him.
But I went looking because I wanted to know more about him.
Couldn't find a Stephen, but Sheldon certainly seems to fit the bill!
