Charles Milles Manson (né Maddox; November 12, 1934 – November 19, 2017) was an American serial killer, cult leader, and musician who led the Manson Family, a cult based in California in the late 1960s and early 1970s. Some cult members committed a series of at least nine murders at four locations in July and August 1969. In 1971, Manson was convicted of first-degree murder and conspiracy to commit murder for the deaths of seven people, including the film actress Sharon Tate. The prosecution contended that, while Manson never directly ordered the murders, his ideology constituted an overt act of conspiracy.
Before the murders, Manson had spent more than half of his life in correctional institutions. While gathering his cult following, he was a singer-songwriter on the fringe of the Los Angeles music industry, chiefly through a chance association with Dennis Wilson of the Beach Boys, who introduced Manson to record producer Terry Melcher. In 1968, the Beach Boys recorded Manson's song "Cease to Exist", renamed "Never Learn Not to Love" as a single B-side, but Manson was uncredited. Afterward, he attempted to secure a record contract through Melcher, but was unsuccessful.
