David Schwimmer was 26 years old when the first season of Friends premiered in 1994. He was born on November 2, 1966, and the first episode of Friends aired on September 22, 1994.
While Schwimmer was the oldest of the main cast members at the time, he played the character of Ross Geller, who was the same age as his on-screen sister, Rachel Green, played by Jennifer Aniston.
This age difference was often a source of humor in the show, as Ross was often portrayed as being more immature and clueless than the other characters.
