He had complications from Parkinson’s disease, said his wife, Shirley Mersereau.

Mr. Mersereau became a registered investment adviser in 1965. Five years later, he founded a firm that merged in the 1970s with Folger, Nolan, Fleming, Douglas, one of Washington’s oldest investment businesses. He was made a senior vice president in 1978.

In 1984, he left to open his own investment advisory firm, now known as Carderock Capital Management.

James Gill Mersereau was born in Harrisburg, Pa., and raised in Washington. He was a 1949 graduate of the private Sidwell Friends School and received a bachelor’s degree in mechanical engineering from Yale University in 1953.

He served in the Air Force from 1953 to 1956. After briefly living in Houston and working for his family’s mechanical contracting firm, he returned to the Washington area in 1959 to work for what is now Bank of America.

His interests included flying and sailing.

Mr. Mersereau was a member of the Society of the Cincinnati, the Chevy Chase Club and the Metropolitan Club. He was a volunteer and trustee of the Kiwanis Club and the Washington Children’s Foundation, a nonprofit organization that supports dis­advantaged children.

Survivors include his wife of 59 years, Shirley Williams Mersereau of Washington; two children, Lynda Elliott of Washington and James W. Mersereau of Bethesda; and five grandchildren.
