Wyman died Wednesday at Brigham and Women's Hospital after a short illness, his family said in a statement. He had surgery Dec. 15 for an abdominal infection.
A graduate of Phillips Academy in Andover and Amherst College, Wyman's business career included stints with Nestle, Polaroid and the Green Giant Co., where he served as president and chief executive until it was acquired by Pillsbury in 1979.
He joined CBS in 1980, became chairman in 1983 and resigned in 1986.
Later, he served on several corporate and philanthropic boards, including those of Amherst, the Ford Foundation and the United Negro College Fund.
Last month, Wyman gave up his 25-year membership at Augusta National to protest its lack of female members. He called the club ``pigheaded'' and said that up to a quarter of its 300 members felt the same way. He also criticized CBS for not speaking out on the event, which the network broadcasts.
The Augusta, Ga., club hosts golf's premier tournament, the Masters. Martha Burk, head of the National Council of Women's Organizations, is leading a campaign to urge the club to admit female members.
Augusta National officials have said Wyman's resignation would not change their policy. The only other member known to have stepped down is John Snow, President Bush's choice to be treasury secretary.
Wyman is survived by the Rev. Dr. Deborah Whiting Little, an Episcopal priest whom he married in November and with whom he lived in Cambridge, as well as three sons and a daughter.
A funeral service was scheduled for Monday in Boston.
