Born and raised in the Sheepshead Bay neighborhood of Brooklyn, N.Y., David got his start in television as a writer on the sketch comedy shows "Fridays" and "Saturday Night Live" in the early 1980s.
In 1989, David and stand-up comic Jerry Seinfeld created the hugely successful situation comedy "Seinfeld." He wrote for and executive produced the show, and is said to be the inspiration for the character of George Constanza.
David stayed with the show for seven years.
The 59-year-old David is nominated for outstanding lead actor in a comedy series for playing himself on "Curb Your Enthusiasm," now in its fifth season.
David created, writes, directs and produces the off-beat HBO show, which is based on his life.
