The family at Scotsdales have announced that their father Mr David Rayner died in the early hours of Saturday morning 14th January.
His daughter Caroline Owen told GTN Xtra: "He was 94 years old and died very peacefully in his sleep. Totally unexpected to be honest.
"A lovely way to go! As a family we could wish for nothing better for him. As such we will celebrate his life."
Scotsdales began when the 14-acre Great Shelford site was acquired by Swaffham Bulbeck farmer David Rayner in 1968.
He was well know for always building something and in 2007 with Caroline, David set up the Scotsdales Charitable Foundation which enabled the building of the Cambridge Cancer Centre in early 2008 on land donated by Mr Rayner.. From start to finish, the building work took just 8 months, and everyone involved in the project worked completely free of charge.
Today, the Cancer Centre’s David Rayner Building is also available to other charitable groups for workshops, lectures, information days and social events.
