"He had five grandchildren, and he attended all of the athletic events from Little League through college, filming their games. He very rarely missed a game," said his daughter, Harriet M. Adam of Severna Park.
"His devotion and loyalty to his family and friends was unmatched, and those who were lucky enough to have known him considered him a true gentleman," his daughter said.
His wife of 60 years, the former Anastasia Characklis, died this year.
Mr. Manis was a member of Sts. Constantine and Helen Greek Orthodox Church, 2747 Riva Road, Annapolis, where funeral services will be held at 11 a.m. Monday.
In addition to his daughter and five grandchildren, Mr. Manis is survived by a son, Nicholas G. Manis of Annapolis.
