Arthur Gladstone, who has died at 78, was an East Riding businessman whose seed company counted the Queen’s Sandringham estate among its clients.
Born in Hull into a family of 12 children, he went to work, after national service, for the Darlington firm Farmway - first as a sales representative in Driffield and then as UK seeds manager, looking after farm accounts from the Humber Bridge to the Scottish borders.
Following a chance meeting with Peter Hurrell, who had formed the Hurrell & Mclean seed business in the 1950s, Mr Gladstone bought the business outright.
His dogged determination saw it acquire as customers Ascot Racecourse and Hull City FC, as well as the royal acres in Norfolk.
He was proud that the firm remained in the hands of family members - especially those of his four grandsons.
A decade ago, he bought North Cattlehomes farm near Driffield, which he also developed into a successful seed growing business.
He is survived by Ann, his wife of 56 years, son Nick, daughter Jo, and his grandsons.
