Claire Brown Kaiser died peacefully on Oct. 27. She was 86.

Born in Philadelphia, Pa., on April 14, 1932 to Charles and Caroline (Liebrecht) Brown, she grew up in Philadelphia.

She attended Girl’s High in Philadelphia and later graduated from the University of Pennsylvania’s Wharton School in 1954. At the time, she was one of a very small number of women to have enrolled in and graduated from the Wharton School.

Claire worked at N.W. Ayer Advertising for a number of years. She and her family spent most of their summers in Ventnor, N.J., where she met John (Rex) Kaiser. They married in 1958 and lived in Wilmington, De., the rest of their lives. They had five children and spent most of their summers in Edgartown on their sailboat, Claire.

Claire thoroughly enjoyed her life, and her marriage to Rex constantly grew to new heights. They both adored each other, and raised their children to cherish and respect each other as well.

As a family, they took numerous ski trips to New England and the Poconos and visited the Jersey shore and sailed the Chesapeake and much of the East Coast. Claire loved skiing, sailing, riding horses, playing cards and gardening.

She became involved with the Barnes Foundation in Philadelphia where she studied horticulture for a number of years. During their early married years, she was involved with the Wilmington Junior League where, among other things, she produced and performed multiple puppet shows with Rex and their dear friend Jack Horty.

Claire and Rex had many friends in many places whom they cherished. Their annual St. Patrick’s Day party never disappointed.

She was predeceased by her husband and a daughter, Annette Kaiser Voorhes, a brother, Charles Brown Jr. and his wife, Sara, and her nephew, Charles Brown 3rd. She is survived by her son John Jr. who was caretaker for her and Rex during the past six years. She is also survived by her son William Kaiser of Manchester, David and Jenn Kaiser of Mattapoisett, Aimee and Paul Satterfield of Donegal, Ireland, and niece, Catherine, and David Heckman of Blue Bell, Pa. She had 11 grandchildren.

Visitation will be at St. Joseph’s on the Brandywine on Nov. 12 at 9:30 a.m. with a funeral mass immediately following at 10:30 a.m.
