What is the first name of Bainbridge? Bainbridge coauthored the paper `Functorial Polymorphism' with Freyd, Scedrov and Scott (DOI). What is his/her first name?
I knew him as a mentor back in the day.  In person he went by "Stewart Bainbridge".  Which also answers the question asked by @a3nm about what the "S" stands for.  I never heard about the "Edwin" so presumably it was a given name he wasn't fond of.
