About this Item

(London, Taylor and Francis, 1902). No wrappers, as extracted from "Proceedings of the Royal Society of London.", Vol. LXX. Pp. 341-344 a. pp. 344-347. First printing of these two importent papers on wireless telegraphy, describing the inventions which made it possible to make the first wireless transmissions across the Atlantic in 1901. Maconi's apparatus was built on a magnetic detector invented by Rutherford, and was called Marconi's "Maggie". A powerfull transmitter was built at Poldu, Cornwall, England, and a large receiving antenna placed at Cape Cod, Massachusetts. Marconi succeeded to receive (on Dec. 12) three code dots, signifying the letter "S". "Already well known, Marconi, et twenty-seven, became world famous overnight."(DSB).Marconi and K.F.
