George Osmond, father of singing siblings The Osmonds, has died aged 90.
George Osmond helped launch the musical careers of his children
He was an early manager of the group and helped launch the careers of six of his eight sons, including Donny and his daughter, Marie.
Osmond died of natural causes at home in Provo, Utah, family spokesman Kevin Sasaki said.
Marie cancelled an appearance on US TV show Dancing With The Stars to fly to Utah with brother Donny to be with their family.
Wyoming-born George Osmond kicked off the family entertainment business by teaching barbershop-quartet harmonies to sons Alan, Wayne, Merrill and Jay, who began singing together at church functions and events in Utah.
On a trip to Los Angeles in the early 1960s, the boys landed a job as Disneyland performers, leading to a TV debut on The Andy Williams Show.
Younger brother Donny joined the group a year later aged six and ultimately became its focal point.
Osmond gave up his insurance and property business in Utah to focus on managing his sons' career in California.
The family members have had a total of 16 UK top 10 hits
The Osmonds released their debut album in 1970 and became chart-toppers with the single One Bad Apple (Don't Spoil the Whole Bunch).
Counting solo records, the Osmond family have released more than 142 records and sold more than 100 million copies in the last 50 years.
Their biggest hits in the UK were Love Me For A Reason and Crazy Horses, both released in the early 1970s, when the group would be mobbed by fans at public appearances.
From 1976 to 1979, Donny and Marie Osmond hosted the TV programme The Donny and Marie Show, which their older brothers helped produce.
In August 2007 the family reunited on stage for the first time in 20 years to mark the 50th anniversary of the family's first foray into showbusiness.
George Osmond is survived by nine children, 55 grandchildren and 48 great-grandchildren.
