In a condolence message, ICC President David Morgan and CEO Haroon Lorgat paid tribute to the former cricket administrator, describing him as a man of extraordinary talent.
"Raj Singh Dungarpur was an extraordinary person with extraordinary talent and ability. He was an institution from which plenty of stars have graduated," the condolence message read.
Affectionately called as 'Rajbhai' in the cricket fraternity, the 73-year-old Dungarpur, who was president of the Cricket Board for three years in the late 1990s, was suffering from Alzheimer's disease.
A bachelor from the Dungarpur royal family of Rajasthan, he was also a former first class cricketer, a former India team manager and ex-chairman of the senior selection panel.
A former president of the Cricket Club of India for 13 years before he took ill last year, Dungarpur died at his residence on Saturday morning.
