Nelson Doubleday Jr.

Nelson Doubleday Jr. (July 20, 1933 – June 17, 2015) was the owner and the next-to-last president and CEO of Doubleday and Company before its sale to Bertelsmann A.G. in 1986. He was instrumental in the company's purchase of the New York Mets in 1980.

After selling Doubleday Publishing, Doubleday personally bought a 50 percent stake in the Mets in 1986, with team president Fred Wilpon buying the remaining 50 percent. Doubleday remained chairman of the board of the Mets, a post which he had held since 1980. In 2002, Doubleday sold his interest in the New York Mets to Wilpon and Wilpon's family, in an acrimonious transaction that saw a dispute over the team's value.
