Tesla's Egg of Columbus Nikola Tesla, at the 1893 World's Columbian Exposition, demonstrated a device he constructed known as the "Egg of Columbus." It was used to demonstrate and explain the principles of the rotating magnetic field model and the induction motor. It was also used to rotate armatures at great distances and speeds in the first demonstration of wireless power transfer.

Deutschland incident (1902) The "Deutschland" incident of 1902 occurred in March of that year with a German passenger steamer from the Hamburg America Line named SS "Deutschland". During a famous passage over the Atlantic, where the ship was carrying Prince Heinrich, the brother of the Kaiser back to Europe from a highly publicized visit to the United States, the steamer was prevented from using her Slaby-d'Arco system of wireless telegraphy as the Marconi radio stations refused its radio traffic through their nets and blocked the rival system. Prince Henry, who tried to send wireless messages to both the US and Germany, was outraged.

Marconi Wireless Telegraph Company of America The Marconi Wireless Telegraph Company of America (commonly called American Marconi) was incorporated in 1899. It was established as a subsidiary of the British Marconi Company and held the U.S. and Cuban rights to Guglielmo Marconi's radio (then called "wireless telegraphy") patents. American Marconi initially primarily operated high-powered land and translatlantic shipboard stations. In 1912, it acquired the extensive assets of the bankrupt United Wireless Telegraph Company, becoming the dominant radio communications provider in the United States.
