Gene Simmons Biography

Gene Simmons was born Chaim Witz on August 25, 1949, in Haifa, Israel, to Jewish refugee parents from Hungary. His mother, Flóra Kovács (later Florence Klein and then Florence Lubowski, 1925–2018), survived Nazi concentration camps, including Mauthausen in Austria, where she was liberated on May 5, 1945. She and her brother, Larry Klein, were the only survivors of their family during the Holocaust. His father, Ferenc “Feri” Yehiel Witz (1925–2002), was a carpenter who married Flóra in 1946; the couple moved to Mandatory Palestine the following year.

Chaim grew up in a modest Jewish household in Tirat Carmel, Israel. After his parents divorced when he was eight, he and his mother immigrated to Queens, New York. There, he became Gene Klein, briefly attended Yeshiva Torah Vodaas, switched to public school, and graduated from Newtown High School.

Gene attended Sullivan County Community College and graduated from Richmond College with a Bachelor of Arts in Education in 1970.

Gene began playing in bands as a teenager. At 15, he joined Lynx (later renamed the Missing Links) in 1964–65. After Lynx, he formed Long Island Sounds and later played in Bullfrog Beer (1969–1970), where he recorded home demos including “Leeta,” later featured on a Kiss box set. In the early 1970s, Gene and future Kiss co-founder Paul Stanley (then Stanley Eisen) played together in Wicked Lester with guitarist Steve Coronel and others, recording one unreleased album for Epic Records. Dissatisfied with the band’s sound and direction, Gene and Paul chose to leave Wicked Lester and their record deal to form what they called the “ultimate rock band.”

More

In 1973, Gene and Paul transitioned from previous musical projects by recruiting drummer Peter Criss (George Peter John Criscuola) from a Village Voice ad and guitarist Ace Frehley (Paul Daniel Frehley), forming Kiss. They debuted with their self-titled album in February 1974. Gene created the “Demon” persona, which featured fire-breathing, blood-spitting, and stage moves inspired by comic books. Kiss became known for their makeup, pyrotechnics, and theatrical live shows. Gene and Paul remained the only constant members through various lineup changes until Kiss’s final show in December 2023.

After achieving musical success, Gene expanded into acting, taking supporting or leading roles in films (Runaway (1984), Trick or Treat (1986), Wanted: Dead or Alive (1987)) and making guest appearances on TV (Miami Vice, Third Watch, CSI). He later transitioned into producing reality television, notably with Gene Simmons Family Jewels (2006–2012), which featured his family, his partner and then-wife Shannon Tweed, and their children. In subsequent years, Gene advanced into the film industry by co-founding Erebus Pictures (2015) and, in May 2023, establishing Simmons/Hamilton Productions with Gary Hamilton for action-thriller film production. Continuing to evolve his public presence, he guest-judged “Hair Metal Night” on Dancing with the Stars in October 2024.

Gene shifted from solely performing to producing, working on albums for artists like Wendy O. Williams, Keel, and Black ‘n Blue, and managing Simmons Records (distributed by RCA). He branched into publishing with Gene Simmons’ Tongue (2002, five issues). His projects diversified further with the 2017 release of The Vault, a $2,000 box set of his works. In 2018, Gene entered the cannabis industry as “Chief Evangelist Officer” and a major investor in Invictus MD Strategies. By 2022, he had engaged with talent shows, judging the Yoshiki Superstar Project X

on Hulu Japan, reflecting a continuous evolution in his career interests.
