Larry David, born July 2, 1947, in Brooklyn, New York, is an American comedian, writer, actor, director, and producer best known for co-creating the landmark sitcom *Seinfeld* (1989–1998) and starring in and creating HBO's *Curb Your Enthusiasm* (2000–2024).[1][2][7] After graduating from the University of Maryland with a history degree in 1970, he worked odd jobs like cab driver and bra salesman before pursuing stand-up comedy in the 1970s and writing for shows including *Fridays* and *Saturday Night Live*.[2][4][5] David co-developed *Seinfeld* with Jerry Seinfeld, serving as head writer and executive producer for its first seven seasons, where he shaped its "show about nothing" style focusing on everyday absurdities and social faux pas—elements drawn from his life, such as incidents mirrored in George Costanza's character.[1][2][7] He occasionally appeared on the show, voicing roles like George Steinbrenner, and returned to write the 1998 finale.[3][6] The series became television's most popular program, earning David two Primetime Emmy Awards in 1993 (for Outstanding Comedy Series and writing the episode "The Contest"), seven additional Emmy nominations, two Writers Guild of America Awards, three Golden Globe nominations, and three Producers Guild Awards.[1][2][6] Leaving *Seinfeld* in 1996, David wrote, directed, and starred in the 1998 film *Sour Grapes*, a critical and commercial disappointment.[1][2][4] He rebounded with the 1999 HBO special *Larry David: Curb Your Enthusiasm*, leading to the long-running semi-improvised series where he played a fictionalized version of himself navigating petty conflicts and social awkwardness; it won a 2003 Golden Globe for Best Comedy Series, earned multiple Emmy and WGA nods, and a 2006 WGA Award.[1][3][6] Other credits include starring in Woody Allen's *Whatever Works* (2009), co-writing and starring in HBO's *Clear History* (2013), his 2015 Broadway play *Fish in the Dark* (with a $13.5 million advance), and *The Three Stooges* remake (2012).[1][3][4] David, who married Laurie Lennard in 1993 (divorced 2007) and has two daughters, remains influential for expanding sitcom boundaries with misanthropic humor admired by peers.[2] (Word count: 298)
