The Unseen Signals traveling exhibit celebrates the life of the unsung genius and IEEE Medal of Honor winner Edwin H. Armstrong by highlighting his technological innovations, patriotism, and the continuing relevance of his achievements. It delves into Armstrong’s intellectual and professional journey against a backdrop of progress in wireless communication. Beginning with an exploration of the humble origins of the radio era during the early 20th century, we invite visitors to immerse themselves in Armstrong’s university years, his military service during the First World War, his alliance with the Radio Corporation of America (RCA), and the rise of the radio broadcasting industry. The IEEE Global Museum presented by the IEEE History Center brings museum-quality traveling exhibits to IEEE members and the public to promote an understanding of electrotechnology and its impact on society. This exhibit will open on 2 November 2024 at the National Museum of Industrial History in Bethlehem, PA. View the flyer for the opening or view the Museum's main collections webpage.
