Dr. Sarah Johnson is an American historian based in the Hudson Valley in New York. She conducts historical research, writes, and lectures about 19th-21st century American history. Her knowledge of American material culture was honed through twenty years of teaching undergraduate and graduate design students to critically analyze objects in museum collections within broader frameworks of culture, communications, and technology so they could become more informed designers and makers of objects. She has extensive public history experience, working with museum collections, local historical societies, and on digital projects to make historical artifacts and images more accessible.
