Guglielmo Marconi Signed Photograph

Early vintage photographic portrait signed in fountain pen by Guglielmo Marconi (1874-1937), Italian inventor and electrical engineer whose pioneering work in wireless telegraphy helped establish the foundations of modern radio communication. Marconi received the Nobel Prize in Physics in 1909, shared with Karl Ferdinand Braun, for their contributions to the development of wireless telegraphy. His work transformed long-distance communication, particularly maritime communications, and played a central role in the emergence of radio technology. The signed photograph is attractively matted and framed with a descriptive plaque. Includes documentation from a previous One of a Kind Collectibles auction held in April 2017. Estimate $1,000 - $1,500
