Sue E. Dalsemer, a former Baltimore Museum of Art docent and world traveler, died Saturday at her New York City residence from Alzheimer's disease. She was 87.

The former Sue Ellen McCaughey was born in Baltimore and raised on East Belvedere Avenue. She was the daughter of Stuart Houston McCaughey, president of M.S. Willett Co., and Edna Louise McCaughey, a bookkeeper.

The M.S. Willett Co., founded by her grandfather and located in Cockeysville, manufactures tools and dies.

She was a 1949 graduate of Eastern High School and received an associate’s degree from Lycoming College in Williamsport, Pa.

While in college, she met and fell in love with David Jones. They married and later moved to a Westminster farm where they restored an antebellum farmhouse. The couple divorced in 1975.

In 1978, she married Gordon H. Dalsemer, who was chairman of Dalsemer, Catzen and Associates, a business consulting firm.

They resided in Roland Park and enjoyed sailing the Chesapeake Bay, the East Coast and Caribbean Sea aboard their boat, My Fair Lady.

Mrs. Dalsemer was a longtime member of the Baltimore Museum of Art. She served as a member of the women’s committee and was a docent specializing in the Cone Sisters Collection and Fauvism.

After her husband’s death in 1984, she moved to London and took art history classes at both Christie’s and Sotheby’s auction galleries. She also studied at Oxford University and at the Institut de Francais in Villefranche-sur-Mer, France.

Her particular interests were medieval iconography and “stories of courtly love,” said her daughter, Deborah Jones Buck of New York City.

Since 1997, Mrs. Dalsemer had lived in Manhattan.

Services are private.

In addition to her daughter, she is survived by a son, David S. Jones of Quicksburg, Va.; and a grandson. Another daughter, Suellen Saunders, died in 2001.
