Mathilde “Mimi” Lee, wife of former Maryland Gov. Blair Lee III, died Tuesday at Laurel Regional Hospital in Maryland.

Mrs. Lee was an avid supporter of the Boal Mansion Museum in Boalsburg, Centre County, Pa., on whose nonprofit board she served from its founding in 1952 until her death. She was the sixth generation of the Boal family at the Boal Mansion and attended most of the special events at the museum.
