Eugene Ellsworth Landy (November 26, 1934 – March 22, 2006) was an American psychotherapist known for his unconventional 24-hour therapy and especially for his treatment of the Beach Boys co-founder Brian Wilson in the 1970s and 1980s.
His treatment of Wilson was deemed unethical by Californian courts and was later dramatized in the 2014 biographical film Love & Mercy, in which Landy is portrayed by Paul Giamatti.
As a teenager, Landy aspired to show business, briefly serving as an early manager for George Benson.
During the 1960s, he began studying psychology, earning his doctorate at the University of Oklahoma.
After moving to Los Angeles, he treated many celebrity clients, including musician Alice Cooper and actors Richard Harris, Rod Steiger, Maureen McCormick, and Gig Young.
He also developed an unorthodox 24-hour regimen intended to stabilize his patients by micromanaging their lives with a team of counselors and doctors.
Brian Wilson initially became a patient under Landy's program in 1975.
Landy was soon discharged due to his burdensome fees.
In 1982, Landy was re-employed as Wilson's therapist, subsequently becoming his executive producer, business manager, co-songwriter, and business adviser.
Landy went on to co-produce Wilson's debut solo album Brian Wilson (1988) and its unreleased follow-up Sweet Insanity (1991), as well as allegedly ghostwriting portions of Wilson's disowned memoir Wouldn't It Be Nice: My Own Story (1991).
In 1989, Landy agreed to let the state of California revoke his professional license amidst accusations of ethical violations and patient misconduct.
Wilson continued to see Landy until a 1992 restraining order barred Landy from contacting the musician ever again.
After the 1990s, Landy continued a psychotherapy practice with licensure in New Mexico and Hawaii until his death.
