Born Louis Szekely (pronounced SEE-kay) in New York City on Sept. 12, 1967, C.K.'s family moved to Mexico shortly after his birth, making Spanish his first language. His heritage was an eclectic mixture of Mexican and Hungarian from his father, and Irish on his mother's side. After six years in Mexico, the family returned to the States and settled into Newton, MA. In grade school, he resorted to going by C.K. when it became clear that "Szekely" was too difficult for anyone to pronounce correctly. Though underage, C.K. began performing in Boston-area comedy clubs during his senior year of high school. In 1990, he moved to New York, continuing to make the rounds on the comedy circuit, as well as gaining exposure by appearing on many televised comedy shows. In the early nineties, C.K. took his talent behind the scenes when he became one of the original writers for "Late Night with Conan O'Brien" (NBC 1993-2009) as well as "The Dana Carvey Show" (ABC, 1996), the latter of which may have been too raunchy for American audiences and was soon canceled.In 1996, C.K. formed two pivotal business relationships - one, with HBO, which gave him his own comedy special, and the second, with comic Chris Rock, who hired him as a writer/producer for "The Chris Rock Show," (HBO 1997-2000), earning C.K. an Emmy in 1998. That same year he wrote and directed his first feature film, "Tomorrow Night," an independent comedy shot in black and white about a loner who marries an elderly woman, only to decide that she has too much baggage and ends up retreating back to his loner ways. His collaboration with Rock provided C.K. with the opportunity to write and direct his first major studio film, the critically maligned cult classic "Pootie Tang" (2001). The film, starring Rock, chronicled the exploits of a crazy musician-actor-folk hero of the ghetto, and was a C.K. idea created for "The Chris Rock Show."As the years went by, the more domesticated C.K. grew with home and family, the more brash his stand-up comedy became. His wife and daughters bore the brunt of his comic wrath, with jokes conceding that he understood why people threw their babies in dumpsters. Even with the comic flying under the radar, HBO continued its lovefest for C.K., commissioning another comedy special from him in 2005. That same year, he was chosen by both Variety and Hollywood Reporter as a comic to watch. 2006 was a benchmark year for C.K. He collaborated yet again with Chris Rock, sharing writing credits on the Rock-directed feature "I Think I Love My Wife" (2007). In June of 2006, HBO debuted its sitcom "Lucky Louie" written, directed, produced by and starring C.K. Based on his real life, the sitcom was unafraid to offend the viewing audience and became famous for its rampant foul language, full-frontal male nudity, and ugly, T-shirt-wearing sex between C.K. and his onscreen wife, Kim (longtime friend Pamela S. Adlon), all daringly performed in front of a live studio audience in the manner of vintage network sitcoms. Unfortunately, the show was canceled by September of that same year.Also that year, the comedian starred in his first hour-long stand-up special, "Louis CK: Shameless." When it aired the following year, its success fueled a cross-country tour where the comedian performed to sold-out venues. He notched several movie credits, including supporting roles in "Diminished Capacity" (2008) alongside Virginia Madsen and Matthew Broderick, "Welcome Home, Roscoe Jenkins" (2008) opposite Martin Lawrence and Mo'Nique, and "Role Models" (2008) with Paul Rudd. He played a larger part as Ricky Gervais' sidekick in the satirical alternate-universe comedy "The Invention of Lying" (2009). C.K. also began recurring on the popular sitcom "Parks and Recreation" (NBC, 2009-15) as a straight-arrow police officer romancing Amy Poehler's Leslie Knope. C.K. continued with his comedy, shooting a second hour-long special of all-new material with "Louis CK: Chewed Up" (2008) and taping "Louis CK: Hilarious" (2010), which he hoped to show theatrically. Fans rejoiced to hear that the comedian had earned another sitcom, "Louie" (FX, 2010-15), a quirkier, moody series that explored more complicated emotions with regular excursions into unexplained surrealism. A critical success that engaged a vociferous cult following, "Louie" gave the comic Emmy nominations for Outstanding Lead Actor in a Comedy Series in 2011 and 2012. In the latter year, C.K. earned two Emmy Awards, one for Outstanding Writing on "Louie" and the other for Outstanding Writing for a Variety Special with "Louie C.K. Live at the Beacon Theatre." He closed out the year with a Golden Globe nod for Best Actor in a Comedy Series. During an extended break between the show's third and fourth seasons, C.K. co-starred in David O. Russell's "American Hustle" (2013) and had a supporting role in Woody Allen's comedy-drama "Blue Jasmine" (2013). "Louie" returned to the air in the summer of 2014. Following appearances in "The Angriest Man in Brooklyn" (2014) and the Blacklist-era biopic "Trumbo" (2015), C.K. announced that "Louie" was going on an indefinite hiatus following its fifth season. C.K. kept busy in a variety of fields, appearing in a lead voice role in the animated hit "The Secret Life of Pets" (2016) and co-creating two series starring longtime friends, Zach Galifianakis' "Baskets" (FX 2017-) and Pamela Adlon's "Better Things" (FX 2016-). He also created a web series set in a Brooklyn bar, "Horace and Pete," which he self-funded and sold through his website, and released another stand-up special, "Louis C.K. 2017" (2017). Keeping with his new creative credo of filming his work in secret, C.K. wrote, directed and co-starred in "I Love You, Daddy" (2017), starring Chloe Grace Moretz as a teenager who begins dating a film director with a well-known predilection for young women, played by John Malkovich. Shot in black and white in conscious homage to Woody Allen's "Manhattan" (1979), the film played the festival circuit in 2017 was set to premiere later that year. In the wake of sexual misconduct allegations against Harvey Weinstein, Kevin Spacey and other Hollywood stars, the New York Times published a story on November 9, 2017 in which five fellow comedians and other industry professionals stated that C.K. had either masturbated in front of them or attempted to pressure them into letting him do so. Some of the stories had been an open secret in the comedy community for years, but this was the first time the women had been identified by name. The following day, C.K. released a statement admitting to the incidents, and distributor The Orchard announced that the release of "I Love You, Daddy" was canceled.
