LEHI, UTAH — Alan Osmond, the oldest member of the singing group The Osmonds, died at his home in Lehi, Utah at 8:30 p.m. MDT on Monday at age 76, according to a family spokesperson. He had been diagnosed with multiple sclerosis in 1987.

Born on June 22, 1949, in Ogden, Utah, Osmond formed a barbershop quartet with his brothers at age 12. He performed alongside his brothers Merrill, Wayne and Jay on a television variety program after the group worked at Disneyland and was discovered by the father of Andy Williams, leading to a seven-year stint on that program.

The brothers later moved to Los Angeles to pursue a music career. Younger brothers Donny and Jimmy joined the group, and they became teen idols. Osmond helped write the Osmonds' hits "One Bad Apple" and "Crazy Horses." "Crazy Horses" peaked at number 14 on the US Billboard Hot 100, reached number two in the UK and was a major hit in Ireland, the Netherlands and Canada. From 1976 to 1979, the Osmonds starred in the television show Donny & Marie with their sister Marie Osmond.

Osmond met Suzanne Pinegar, a cheerleader, at a Brigham Young University basketball game and had their first date at Y Mountain in Utah. The couple married on July 16, 1974, at the Provo LDS Temple. He performed two gigs in Las Vegas on the night of his wedding.

His illness forced him to retire from live performing. "I was on stage and couldn't raise my right hand. I trusted my Heavenly Father. You have to have opposition in life — this was my test," he said of his diagnosis. He also said, "I may have MS, but MS does not have me!"

Osmond is survived by his wife Suzanne and eight sons: Michael, Nathan, Doug, David, Scott, Jon, Alex and Tyler. His son David appeared on the eighth season of "American Idol" and was diagnosed with multiple sclerosis in 2005. He was predeceased by his brother Wayne Osmond, who died in January 2025.

Merrill Osmond wrote on Facebook about his final visit with his brother. "I was blessed to sit quietly with him. We talked as brothers do, heart to heart. He was struggling, but when I shared a joke or two, he found the strength to chuckle … and then he smiled," he wrote.

Donny Osmond posted a tribute on Instagram reflecting on a childhood photograph. "Even back then, you can see that he had his arm around me, watching over me. That's who he was. My protector. My guide. The one who quietly carried so much responsibility so the rest of us could shine," he wrote.
