Can anybody name all the real people's names who were used as characters on Seinfeld? I know there were quite a few. For instance, Lloyd Braun.

Prob too many to list!

Kramer
Elaine Benes
Sid Fields ...

Alec Berg was a writer for the show.
Steve Lookner was writer for the show (Beth Lookner, The Wait Out +).

Ruthie Cohen plays the cahsier at Monk's, named "Ruthie Cohen."

Not too, too many where a real persons name was used a character.

Elaine Benes?

Corrected I stand....

according to TBS, character "Elaine" was named after Tery Benes, a woman Larry David once dated.
