Biography: David Krumholtz (born May 15, 1978 in Queens, New York) is an American actor who currently stars in the CBS television show NUMB3RS.
David Krumholtz began his acting career at the age of 13 when he followed his friends to an open audition for the Broadway play Conversations with my Father (1992). He won the role of Young Charlie opposite Tony-winner Judd Hirsch, and actors Tony Shalhoub and Jason Biggs (also making his Broadway debut).
Soon after his run on Broadway, David co-starred in two feature films – Life With Mikey (1993) opposite Michael J. Fox and Addams Family Values (1993) opposite Christina Ricci. For his role in Mikey, David was nominated for a 1993 Young Artist Award.  Although his work in these two films garnered him critical attention, David is probably best known by children and the young-at-heart as the sarcastic head elf Bernard from The Santa Clause (1994) and its 2002 sequel The Santa Clause 2.
In 1994, David co-starred in his first television series, “Monty”, with Henry Winkler. The show only lasted a few episodes. David would star in several short-lived series over the years. He did a number television pilots, some of which made it to the air, and none of which lasted more than 13 episodes. Along the way, he had the opportunity to work with Jason Bateman (“Chicago Sons”, 1997), Tom Selleck (“The Closer”, 1998), Jon Cryer (“The Trouble with Normal”, 2000), and Rob Lowe (“The Lyon's Den”, 2003). It wasn’t until CBS renewed "NUMB3RS" for a 2005-2006 second season that David got the opportunity to film a fourteenth episode of a television series (production began July 25, 2005). Along with his starring roles on television, David made memorable guest appearances on "ER", "Law and Order", "Undeclared", "Lucky", and "Freaks and Geeks."
David amassed a healthy filmography in addition to his television work. He broke out of the children’s movie genre with The Ice Storm (1997), directed by Ang Lee, and Slums of Beverly Hills (1998), starring Alan Arkin and Natasha Lyonne. In 1999, David starred as Joseph Gordon-Levitt's Shakespeare-costumed friend, Michael Eckman, in the popular teen movie 10 Things I Hate About You. That same year, he portrayed a completely different teen character – that of Yussel, a young conflicted Jewish man in Liberty Heights.
It was the role of Yussel that brought David to the attention of actor and filmmaker Edward Burns, who then cast him in the 2001 independent movie Sidewalks of New York.  Playing the romantic and slightly obsessive Benny, David was on a path to larger, more complex film roles. His first role as a leading man came in 2002, when he played opposite Milla Jovovich in the romantic comedy You Stupid Man. Although David carried the film, most never got a chance to see the movie, which was released only in Europe and parts of Asia. It wasn’t until Big Shot: Confessions of a Campus Bookie premiered on FX Networks that America got to see David in a leading role.
Big Shot was a true story based on the Arizona State University basketball fixing scandal of the Early 1990s. David played Benny Silman, a college student and campus bookmaker who was jailed for his part in shaving points off key ASU basketball games. Benny was unlike any character David played prior, and he carried the entire film on his shoulders with much success. He garnered critical praise and proved that he was not just a sidekick. 
In 2004, David again played lead, this time reuniting with Edward Burns for the independent film The Last Hold-Outs. The following year he played Max in Max and Grace, where he once again starred opposite actress Natasha Lyonne. David also returned to smaller key roles in the successful films Ray and Harold and Kumar Go to White Castle – two very different movies released in 2004. In September of 2005, he will be seen in Joss Whedon's science fiction blockbuster Serenity as Mr. Universe.
Right now, David is enjoying his time working on “NUMB3RS.” He plays Charlie Eppes, a mathematical genius who helps his brother Don (Rob Morrow), an FBI agent, solve crimes using math.  "NUMB3RS" features an outstanding cast, including Judd Hirsch, the man who gave David his start in acting back in 1992 on the Broadway stage. Television critic Matt Roush (TV Guide) called David’s work on NUMB3RS “probably his best TV work to date.”
David currently resides in Los Angeles, California where he films "NUMB3RS."
