Well, to make a long story short, David Schwimmer is Jewish!
Since David Schwimmer's mother is Jewish, and in Orthodox Judaism and Conservative Judaism, those with a Jewish mother (or those who underwent a halakhic conversion) are considered Jewish, then that makes him Jewish. His father is Jewish too.
David Schwimmer (whose full birth name is David Lawrence Schwimmer) was born on November 2, 1966 in Flushing, Queens, New York City.
Schwimmer gained worldwide recognition for playing Ross Geller in the sitcom Friends.
