Technical Sergeant Leonard Phillip Matlovich was an American Vietnam War veteran, race relations instructor, and recipient of the Purple Heart and the Bronze Star. He was the first gay service member to purposely out himself to the military to fight their ban on gays, and perhaps the best-known openly gay man in the United States of America in the 1970s next to Harvey Milk. His fight to stay in the United States Air Force after coming out of the closet became a cause célèbre around which the gay community rallied. His case resulted in articles in newspapers and magazines throughout the country, numerous television interviews, and a television movie on NBC. His photograph appeared on the cover of the September 8, 1975, issue of Time magazine, making him a symbol for thousands of gay and lesbian servicemembers and gay people generally. Matlovich was the first named openly gay person to appear on the cover of a U.S. newsmagazine. According to author Randy Shilts, "It marked the first time the young gay movement had made the cover of a major newsweekly. To a movement still struggling for legitimacy, the event was a major turning point."

Coming out of the closet, often shortened to coming out, is a metaphor used to describe LGBT people's self-disclosure of their sexual orientation, romantic orientation or gender identity.
