Preferably, they have some other connection to each other (nationality, discipline, occupation, etc.). This is inspired by the recent deaths of Antonioni and Bergman. I’m not talking about mid-level celebrities, but highly visible, household names. Ones I have so far:
John Adams & Thomas Jefferson
C.S. Lewis & Aldous Huxley (plus JFK)
Yul Brynner & Orson Welles
Joseph Stalin & Sergei Prokofiev
Sammy Davis Jr. & Jim Henson
I’m sure there are a lot more, but I was hoping to limit things to really big names.
