Dr. Ross Eustace Geller, Ph.D. is a fictional character on the popular US television sitcom Friends (1994–2004), portrayed by David Schwimmer.
He was born to Jack and Judy Geller and raised by them on Long Island, New York. He is the older brother of Monica, and attended the same high school as Rachel (as did Monica) where he eventually developed a crush on her which he kept to himself. He befriended a student named Will Colbert, who was frequently bullied by Rachel. Dealing with the fact that she never seemed to notice his feelings for her in a very immature way, Ross co-founded a "We-Hate-Rachel" Club with Will. To spite her, the two of them spread a rumour about her that everyone in the entire high school (apart from Rachel herself) heard about, the rumour in question being that she, as Ross put it, "had both male and female reproductive parts" and that, as Will put it, "her parents flipped a coin and decided to raise her as a girl." Ironically, Rachel unknowingly returned the favour in a way after catching Ross making out with Lincoln High School's fifty year old librarian, when she spread a rumour regarding this all over the high school (although Ross apparently didn't know that she'd seen him doing this or that everyone in the high school knew about it until many years later). In college, he met Chandler, and they became best friends. Later in life, Ross met and fell in love with Carol Willick. Drifting apart from Rachel over time, he and Carol were happily married until she fell in love with another woman, culminating in their divorce.
