Early life and education
Early life and education
Clark was born Marcia Rachel Kleks on August 31, 1953, in Alameda, California the daughter of Rozlyn (Masur) and Abraham Kleks. Both of her parents are of Jewish origins. Her father was born in Mandatory Palestine and raised there and in Israel, and worked as a chemist for the FDA. Because of her father's job, the family moved several times, including living in California, New York, Michigan, and Maryland. Clark graduated from Susan E. Wagner High School, a public school in the Manor Heights section of Staten Island, New York City. She studied at the University of California, Los Angeles, graduating in 1976 with a degree in political science, and then earned a Juris Doctor degree at Southwestern University School of Law.
Attorney
Attorney
Clark was admitted to the State Bar of California in 1979, where she continued to practice law. She worked in private practice and as a public defender for the city of Los Angeles before she became a prosecutor in 1981. She worked as a deputy district attorney for Los Angeles County, California and was mentored by prosecutor Harvey Giss. Clark is well known as the lead prosecutor in the 1995 trial of O. J. Simpson for the murders of his ex-wife Nicole Brown Simpson and her friend Ron Goldman. Prior to the Simpson trial, Clark's highest-profile trial occurred in 1991 when she prosecuted Robert John Bardo for the murder of television star Rebecca Schaeffer. Clark said that the media attention that she received during the trial was "the hell of the trial," calling herself "famous in a way that was kind of terrifying." Clark was advised by a jury consultant to "talk softer, dress softer, wear pastels" in order to improve her image. She subsequently changed her hairstyle into a perm, and the Los Angeles Times described her as resembling "Sigourney Weaver, only more professional." The New York Times commented that "the transformation was not entirely seamless."

Media appearances
In August 2013, Clark appeared as attorney Sidney Barnes in the Pretty Little Liars episode on Freeform (formally ABC) titled "Now You See Me, Now You Don't". In 2015, Clark was parodied on the sitcom Unbreakable Kimmy Schmidt through the character Marcia, implied to represent Marcia Clark in a relationship with Chris Darden. The character portrayed by Tina Fey, whose performance earned her a Primetime Emmy Award for Outstanding Guest Actress in a Comedy Series for the role. Clark appears in the 2016 documentary miniseries O.J.: Made in America. That same year, she was portrayed by Sarah Paulson in the 2016 television series The People v. O. J. Simpson: American Crime Story, which focuses on the Simpson trial. Paulson's performance as Clark earned wide acclaim, and she earned a Primetime Emmy Award and a Golden Globe Award for the role. Clark attended the Emmy Awards with Paulson on September 18, 2016. Katey Rich wrote in Vanity Fair that the series positions Clark as a "feminist hero." In 2019, Clark appeared in the 18th season finale of Gordon Ramsay's reality series Hell's Kitchen as a VIP guest diner for winner and season 6 veteran Ariel Contreras-Fox. In 2024, Clark appeared on the third episode of comedian John Mulaney’s live comedy special Everybody’s in LA. While the episode was themed to and titled "Helicopters," much of the discussion focused around the 1994 O.J. Simpson trial due to the presence of Clark and reporter Zoey Tur, who famously captured helicopter footage of the slow-speed Bronco chase. Clark and Tur had never met before their appearance on the show.
Personal life
Personal life
When Clark was 17 years old, she was raped on a trip to Israel. She has said that it was an experience with which she did not deal until later in life and that it greatly influenced her decision to become a prosecutor. In 1976, Clark married Gabriel Horowitz, an Israeli professional backgammon player whom she had met as a student at UCLA. They obtained a "Mexican divorce" in 1980 and had no children. Horowitz was briefly in the news after he sold topless photos of Clark to the National Enquirer during the Simpson trial. In 1980, Clark married her second husband, Gordon Clark, a computer programmer and systems administrator who was employed at the Church of Scientology. They were divorced in 1995 and had two sons. Gordon argued at a custody hearing during the Simpson trial that he should receive full custody of their children given the long hours that Marcia had spent working for the trial. Clark no longer considers herself religious, although she was raised Jewish and her first wedding was a Conservative Jewish ceremony. She was a member of the Church of Scientology until 1980. Clark resides in Calabasas, California.
