Large Signed Photograph of Guglielmo Marconi, Inventor of the Radio, Dressed in his Uniform as Head of the Radio Service of the Italian Army During World War I

Guglielmo Marconi sent and received his first radio signal in Italy in 1895, proving the feasibility of radio communication. He is credited with others as inventing a system of sending radio signals via wireless telegraphy.  By 1899 he flashed the first wireless signal across the English Channel.  On December 17, 1902, a transmission from the Marconi station in Glace Bay, Nova Scotia, Canada, became the first radio message to cross the Atlantic from North America. In 1901, Marconi built a station near South Wellfleet, Massachusetts that on January 18, 1903 sent a message of greetings from Theodore Roosevelt, the President of the United States, to King Edward VII of the United Kingdom, marking the first transatlantic radio transmission originating in the United States. This station also was one of the first to receive the distress signals coming from the RMS Titanic.

In 1914, Marconi was made a Senator in the Italian Senate and appointed Honorary Knight Grand Cross of the Royal Victorian Order in the UK. During World War I, Italy joined the Allied side of the conflict, and Marconi was placed in charge of the Italian military's radio service. He attained the rank of lieutenant in the Italian Army and commander in the Italian Navy.

Large photograph, signed, of Marconi dressed in his Italian military uniform as head of wireless telegraphy, likely between 1915 and 1918, measuring 5.5 inches by 8 inches and 10.5 inches by 12.8 inches in the frame. 

The majority of Marconi signed photographs are closer to postcard size, this being also in beautiful condition.
