Tributes have been paid to David Robinson, left, who edited Lincolnshire Life until 1989 and also wrote more than 20 books about the county.
He had also helped establish the Lincolnshire Wildlife Trust and served as its president.
A statement from the Trust said it would miss “his devotion to nature conservation”.
His friend John Gill added: “He was out of this world. What he knew about Lincolnshire and Louth was nobody’s business.
“He had a tremendous knowledge. I wish I knew half that he knew. He was a rare species these days. He really was a fantastic gentleman.”
David died on Tuesday 26 July at Diana Princess of Wales Hospital, in Grimsby, after a short illness.
He leaves behind a brother, Ralph, who lives in Canada, son and daughter Christopher and Hilary, granddaughter Michelle and great-grandchildren Tyler and Jayden.
