Ann Conolly Hughey, 90, an authority on the French-born artist and illustrator Edmund Dulac, died March 18 at Suburban Hospital in Bethesda. She was a Potomac resident.
She had congestive heart failure, her daughter, Ann Hughey, said.
Mrs. Hughey, who was trained as a lawyer, later developed an interest in the art of Dulac, who lived from 1882 to 1953. She published a bibliography of his illustrations in 1995 and appeared on a public television program about Dulac and was a consultant to Christie’s and Sotheby’s auction houses.
Ann Conolly was born in Boston. Her father, Richard Lansing Conolly, was a Navy admiral, and she lived in Washington and Annapolis during her youth.
She was a 1943 graduate of Wellesley College in Massachusetts and worked for a naval intelligence unit in Washington during World War II.
She christened the USS Conolly, a destroyer named for her father, and was a member of the Society of Sponsors, a charitable organization composed of people who have christened Navy ships.
Mrs. Hughey graduated at the top of her class from Temple University’s law school in Philadelphia in 1956 but did not practice law.
She was president of an island trust on Monhegan Island, Maine, where she spent her summers. She was a member of the Smithsonian Women’s Committee, the Sulgrave Club, the Colonial Dames and the American Boxwood Society.
Her husband of 60 years, George H. Hughey Jr., died in 2006.
Survivors include a daughter, Ann Hughey of Potomac; and two grandchildren.
