A student of American painter Arthur B. Carles, Piper skillfully embraced the use of vibrant colors to abstractly depict her subjects ranging from still lifes to landscapes. Piper's distinctive and innovative use of white sets her apart from her contemporaries. The white transcends its conventional role, serving simultaneously as a solid presence, spatial void, a counterweight, and a source of ethereal light. Piper’s work not only exudes an irresistible allure but stands as a serious intellectual contribution to the narrative of American Abstraction. Recognized by colleagues and critics alike as one of Philadelphia’s foremost painters and teachers, she enjoyed a career that spanned fifty years and included thirty-five solo shows.
