Margaret Dunning, a Plymouth philanthropist and car enthusiast known for her trademark 1930 Packard 740 roadster, turned 102 on Tuesday.
Plymouth Historical Museum Director Elizabeth Kerstens said Dunning remains one of the community's most active residents and was integral in the formation of the local museum.
"Margaret has been the museum's benefactor," Kerstens said. "She built the museum. She donated the money for the museum, as it stands today, to be built. Without her, we wouldn't have this wonderful museum."
Museum officials will hold a private event Thursday to honor both Dunning's 102nd birthday and the museum's 50th birthday, while previewing the museum's forthcoming Inaugural Gowns of the First Ladies special exhibit.
