Nelson Doubleday Jr., who shortly after taking over his family’s publishing business used it in 1980 to buy the lowly New York Mets and put the team on course to win the World Series in 1986, died on Tuesday at his home in Locust Valley, N.Y. He was 81.
The cause was pneumonia, his son-in-law John Havens said.
Books and baseball defined Mr. Doubleday’s life. He was the grandson of Frank Nelson Doubleday, who founded the publishing company bearing his name in 1896, and the son of Nelson Doubleday, who built the business into a mass-market powerhouse.
