The Marconi company bought Edison’s patent,
“Means for Transmitting Signals Electrically,” No.
465,971, to help indemnify themselves against the patent war that
cast its shadow over them as World War II approached. Marconi did
not make it easier when he joined the Italian Fascist party in
1923 and served Benito Mussolini on the Fascist Grand Council.
