Gale Sandra Klinetsky (August 28, 1940 – February 3, 2014), known professionally as Gloria Leonard, was an American pornographic film actress and publisher of High Society magazine. As a board member of Adult Video Association and its successor the Free Speech Coalition, Leonard was an outspoken advocate for the adult film industry and free speech rights.

According to pornographic film historian Ashley West, publisher of The Rialto Report, Leonard worked for a Wall Street brokerage firm in the 1960s before moving on to work in public relations, including a stint writing copy for Elektra Records in New York's West Village. Upon her return to New York, looking for work, she contacted casting agent Dorothy Palmer, who apparently failed to tell Leonard that the acting role she cast her in was for an adult film.

Leonard began appearing in hardcore pornography in 1974 and appeared in approximately 40 film/projects from 1976 to 1984, in films including Odyssey: The Ultimate Trip (1977), directed by Gerard Damiano, The Trouble With Young Stuff, All About Gloria Leonard (both of which were written and directed by Joseph W. Sarno), Fortune Smiles, Maraschino Cherry and Taboo: American Style. She is best known for her role in The Opening of Misty Beethoven, Radley Metzger’s erotic reimagining of George Bernard Shaw’s play Pygmalion. She retired from acting in 1984.^{[citation needed]}

In 1977, she was hired as the publisher of High Society magazine, a position she held for 14 years while continuing to act and appear in films. She was hired by the magazine's publisher Carl Ruderman, who wanted a female publisher of a men's magazine. Adult-industry historian Ashley West stated in an interview that Ruderman expected her to be a figurehead, but that she took the position seriously. West said, "Gloria really would visit wholesalers herself, had relationships with all the distributors, would hire and fire staff, would supervise layouts, would recommend and decide upon the content, so really became a hands-on editor, at least in the first five or six years of her stint at High Society."

Leonard is also credited with two successful ideas that each became cottage industries, the publishing of nude celebrity photos and phone sex lines. Starting out as a feature that showcased risqué photos of celebrities like Jodie Foster and Goldie Hawn, usually lifted from film stills, the former became a spin-off venture of High Society called Celebrity Skin magazine in 1986. Over its 25-year run Margot Kidder, Ann-Margret and Barbra Streisand unsuccessfully attempted to sue the magazine after it published nude photos of them.

Leonard is credited with being one of the first people to use "976 numbers" for promotional purposes and as a revenue stream: this later became known as the "phone sex" industry. Initially Leonard recorded her own voice informing callers of the contents of the next issue of High Society magazine before its publication. Later she recorded others, such as Annie Sprinkle, "talking sexy". Leonard convinced magazine owner Ruderman to purchase more of these numbers and the business began to be successful using the magazine to promote the service.

Early in her career she was interviewed by a magazine for an article titled "The Parkway All-Stars" (after the Mosholu Parkway in the Bronx) about a group of overachievers who grew up within a 15-block radius. The article also featured interviews with actor Robert Klein, actress Penny Marshall and her brother, television producer Garry Marshall, and fashion designers Calvin Klein and Ralph Lauren. Fellow actress Veronica Vera recalled Leonard saying, "Yeah, I knew Ralph Lauren when he was Ralph Lipschitz [sic]."

Leonard was also presenter at an awards ceremony for Video Review magazine that was emceed by Klein. She recalled in an interview, "When he introduced me he told the audience, 'For 15 years I walked to school with this woman and I saw more of her in three minutes of Misty Beethoven than I saw in all of those 15 years.'"
