In 1993, McDavid started a foundation after Huntington Bancshares Incorporated purchased his family bank, the National Bank of Commerce. The McDavid Foundation has raised money to benefit state children's charities.
He also served as a trustee to the University of Charleston, serving as chairman of the board. He served on two presidential search committees at UC. Further, he was a trustee of Charleston Area Medical Center's Foundation board and a member of the steering committee to raise funds for the hospital's David Lee Cancer Center, which is to be built at the former Watt Powell Park on MacCorkle Avenue.
He was an active member of the Business and Industrial Development Corporation and served the Salvation Army Boys Club and the Rotary Club of Charleston.
Heywood said that McDavid had left the law firm, the firm's clients and his community each better than he found them.
"I think everyone would recall Bill as the ultimate gentleman," Heywood said.
McDavid is survived by his wife, Diana, two sons, one daughter and four grandchildren, among other family members.
Service will be held 3 p.m. Saturday at St. Marks United Methodist Church with Rev. Monty Brown officiating. A reception will be held afterward from 4:30 p.m. to 6:30 p.m. at Berry Hills Country Club.
