David Krumholtz is an American actor born on May 15, 1978, in Queens, New York City. He is best known for playing the math genius Charlie Eppes on the CBS drama Numb3rs and for his role as physicist Isidor Isaac Rabi in Christopher Nolan’s Oscar-winning blockbuster Oppenheimer (2023).
Over a career spanning more than three decades, Krumholtz has proven himself one of Hollywood’s most dependable character actors, popping up in everything from cult comedies to Tony Award-winning Broadway plays.
Who is David Krumholtz?
David Krumholtz is an American actor and comedian who has worked steadily in film, television, and theater since the early 1990s.
He belongs to a generation of performers who never quite became household names but remain instantly recognizable faces across dozens of beloved projects.
His career stretches from a beloved holiday franchise to one of the biggest films of the decade.
Krumholtz first caught the public’s attention as Bernard the Elf in The Santa Clause (1994), a role he returned to nearly three decades later.
His television peak came with six seasons as the lead on Numb3rs, the CBS procedural where he played a math prodigy helping the FBI crack cases. That performance showed a range that his earlier work had only hinted at.
In more recent years, Oppenheimer brought him to a new generation of viewers. His portrayal of the Nobel Prize-winning physicist Isidor Isaac Rabi stood out even amid one of the most star-packed casts in recent memory.
As a member of the SAG Award-winning ensemble, Krumholtz finally received the broader recognition his work had long deserved.
He has also made his mark on Broadway twice, most recently in Tom Stoppard’s Leopoldstadt (2022), earning a Drama League Award nomination for his performance.
Krumholtz continues to work across film, television, and stage, showing no signs of slowing down.
Early Life of David Krumholtz
David Krumholtz grew up in a working-class Jewish household in Queens, New York. His father, Michael, worked as a postal worker, and his mother, Judy, was a dental assistant.
He has described his upbringing as “very working-class, almost poor,” but also warm and culturally rich.
His paternal grandparents had emigrated from Poland. His mother came to the United States in 1956 from Hungary during the Hungarian Revolution.
That family history of displacement and resilience would later inform some of his most personal stage work.

David Krumholtz Ethnicity and Nationality
David Krumholtz is American. He is of Jewish heritage, with roots in Poland on his father’s side and Hungary on his mother’s.
Krumholtz has spoken publicly about his Jewish identity, and it has shaped many of the roles he has chosen throughout his career, including his deeply personal turn in Leopoldstadt.
David Krumholtz Height and Weight
David Krumholtz stands 5 feet 6 inches tall (1.68 meters), according to IMDb. His weight is not consistently reported in reliable sources and has fluctuated significantly in recent years due to health challenges he has spoken about publicly.
David Krumholtz Education
Krumholtz attended P.S. 196 and then Stephen A. Halsey Junior High School 157 in Queens. He briefly enrolled at Forest Hills High School before his acting career took off and redirected his life entirely.
At just 13 years old, he tagged along with friends to an open audition for a Broadway play and walked out with a role.
Formal education gave way to an education in craft. Working alongside stage veterans and seasoned film directors from his early teens gave Krumholtz a real-world training that no classroom could replicate.
David Krumholtz Career
Krumholtz launched his career at the age of 13 when he auditioned on a whim for the Broadway drama Conversations with My Father (1992).
He landed the role of Young Charlie, acting opposite Judd Hirsch and Tony Shalhoub. It was a striking debut for someone who had never acted professionally before.
Early Career
Film roles followed quickly. He appeared in Life with Mikey (1993) alongside Michael J. Fox and earned a Young Artist Award nomination for his work.
That same year, Addams Family Values (1993) gave him a supporting role that introduced him to a much wider audience.
However, it was The Santa Clause (1994) that turned him into a childhood favorite, playing Bernard the wisecracking head elf alongside Tim Allen.
Throughout the late 1990s, Krumholtz expanded his range steadily. He delivered a quiet, lived-in performance in Ang Lee’s The Ice Storm (1997).
He followed that with Slums of Beverly Hills (1998) and the popular teen comedy 10 Things I Hate About You (1999), where he appeared alongside Heath Ledger and Julia Stiles.
Also in 1999, Harold and Kumar Go to White Castle (2004) began a trilogy that showcased his effortless comic timing.
Breakthrough Roles
The CBS series Numb3rs, which ran from 2005 to 2010, was the defining chapter of Krumholtz’s television career.
He played Charlie Eppes, a mathematical genius who helps his FBI agent brother solve crimes by applying complex equations to real-world problems.
TV Guide’s Matt Roush called his performance “probably his best TV work to date.” The show ran for six seasons and over 100 episodes, cementing Krumholtz as a reliable lead in prestige network television.
During this period, he also appeared in the Joss Whedon cult science fiction film Serenity (2005), playing the hacker character Mr. Universe.
Superbad (2007) brought another fan-favorite turn. He carried these supporting roles with a natural ease that made him a go-to choice for directors seeking a performer who could elevate small parts.
Recent Work
After Numb3rs ended, Krumholtz kept busy with a string of supporting roles in major productions. He appeared in two Coen Brothers films, Hail, Caesar! (2016) and The Ballad of Buster Scruggs (2018).
He took on a recurring role as Harvey Wasserman in HBO’s The Deuce (2017 to 2019) and played Monty Levin in the HBO miniseries The Plot Against America (2020).
His return to Broadway in Leopoldstadt (2022) proved to be a career milestone. Playing Hermann Merz in Tom Stoppard’s deeply personal Holocaust drama at the Longacre Theater, Variety described his work as “vulnerable and powerful.”
He earned a Drama League Award nomination for Outstanding Performance, and the production won the Tony Award for Best Play.
In 2023, Oppenheimer elevated his profile dramatically. Playing Nobel Prize-winning physicist Isidor Isaac Rabi, Krumholtz was part of the SAG Award-winning ensemble that took home Outstanding Performance by a Cast at the 30th Screen Actors Guild Awards in February 2024.
Most recently, he appeared in the Apple TV+ hit comedy series The Studio (2025) alongside Seth Rogen and Catherine O’Hara, and he is set to star in the dark comedy film Forelock.

David Krumholtz Awards and Recognition

As part of the Oppenheimer ensemble, he shared in the SAG Award for Outstanding Performance by a Cast in a Motion Picture at the 2024 ceremony.

David Krumholtz Health Struggles
In October 2024, the New York Times published an in-depth report on the risks of heavy cannabis use, and Krumholtz spoke candidly as one of its subjects.
He revealed that he had developed cannabinoid hyperemesis syndrome, a condition caused by prolonged heavy cannabis use that led to severe vomiting, multiple hospitalizations, and a weight loss of more than 100 pounds.
Krumholtz disclosed that he has since stopped using marijuana entirely and is in recovery. The interview was notable for its honesty. Krumholtz described the condition as something that “took over everything.”
His willingness to speak publicly about a health issue tied to substance use was seen by many as a responsible act, particularly given how rarely cannabis-related health risks are discussed openly by public figures.
David Krumholtz Controversy
In August 2026, Krumholtz went viral after posting on Threads that he was stepping away from acting. He described himself as “frustrated, fed up, fried” and said the profession “has lost its gleam.”
He also warned that continuing would mean competing for roles that exploit his talent for diminishing pay, adding that “exploitative art isn’t art.”
The posts were deleted but had already been picked up by Deadline, Variety, and the Hollywood Reporter.
On August 19, 2026, he clarified on Instagram that he had never said “retiring” or “quitting,” only that his career was on hold. He added that he felt “deeply” moved by the outpouring of public support.
The episode sparked a wider conversation about the financial pressures facing character actors in the streaming era, where pay structures have shifted sharply since the network television days that defined Krumholtz’s peak earning years.
David Krumholtz Wife
David Krumholtz married actress and writer Vanessa Britting on May 22, 2010, at The Plaza Hotel in New York City.
The couple had been engaged since July 2008, following five years together. Britting is known for her appearances in Without a Trace (2002) and The Unit (2006).
The couple moved from Los Angeles to Wyckoff, New Jersey in 2017. Krumholtz has spoken warmly about the move and about his connection to the state in interviews with NJ.com and New Jersey Monthly. The marriage appears strong and continues to this day.
David Krumholtz Children
David Krumholtz and Vanessa Britting have two children together, a daughter and a son, both born during the 2010s.
The couple has kept their children largely out of the public eye, and specific names and birth dates have not been confirmed in major sources. Krumholtz has mentioned his family in interviews but chooses to maintain their privacy.
David Krumholtz Net Worth
David Krumholtz’s estimated net worth is $2 million as of 2026, according to Celebrity Net Worth. His income comes primarily from over three decades of consistent work as a character actor across film, television, and theater.
His six-season lead role on Numb3rs was the cornerstone of his earning years, with over 100 episodes on a major network drama contributing significantly to his career earnings.
Film work across franchises like The Santa Clause and Harold and Kumar, along with prestige projects including Oppenheimer and The Deuce, has added to that foundation over time.
Real Estate
Krumholtz’s real estate history offers a candid window into the financial volatility he has spoken about publicly. In April 2006, he paid $1.715 million for a home in Los Angeles. He sold it in August 2010 for $1.325 million, taking a loss.
Three months later he purchased a home in LA’s Larchmont Village neighborhood for $2.149 million, then sold it in August 2012 for $1.5 million.
More recently, Krumholtz and his wife paid $419,000 for a home in Teaneck, New Jersey in 2017, which they sold in January 2026 for $599,000.
The pattern of buying high and selling low during the Numb3rs peak years aligns with his own admissions about spending lavishly when money arrived suddenly and losing significant value on his Hollywood Hills property.
Despite a long and productive career, the combination of those losses and the structural shift in actor pay in the streaming era helps explain why financial security has remained a real concern for him.
