Henry Stamford Thirsk, 74, passed away at Everingham, near Pocklington, on April 20 and his death is being treated as 'unexplained'.
No further details of the nature of the incident have yet been revealed by Humberside Police, who are investigating.
Mr Thirsk is listed with Companies House as the director of two real estate and property development businesses run from Pocklington. He gave his occupation as a farmer of Groves Farm, an arable enterprise.
He also owned the Feathers Hotel and was a keen supporter of the town's rugby and football clubs, having donated land for the latter to build pitches on.
He was a keen shot and tributes have been left by friends from the field sports community.
David Sheldrake said: "RIP Henry Thirsk, one of the true gentlemen of the shooting world I have been lucky to have shot with. May the grouse fly quickly and the pheasants fly high."
Allan Carr added: "RIP Henry Thirsk, a true legend in the shooting world. You will sadly be missed and you were always fun to be around."
Dave Carrie commented: "A renowned shooting character who will sadly be missed."
