Guglielmo Giovanni Maria Marconi [11] [12] was born in Palazzo Marescalchi in Bologna on 25 April 1874, the second son of Giuseppe Marconi (an Italian aristocratic landowner from Porretta Terme who lived in the countryside of Pontecchio) and his Irish wife Annie Jameson (daughter of Andrew Jameson of Daphne Castle in County Wexford, sister of Scottish naturalist James Sligo Jameson, and ...
[1] [2] Developed in 1902 by radio pioneer Guglielmo Marconi [1] [2] [3] from a method invented in 1895 by New Zealand physicist Ernest Rutherford, [4] it was used in Marconi wireless stations until around 1912, when it was superseded by vacuum tubes. [5] It was widely used on ships because of its reliability and insensitivity to vibration.
Guglielmo Marconi. Guglielmo Marconi studied at the Leghorn Technical School, and acquainted himself with the published writings of Professor Augusto Righi of the University of Bologna. [97] In 1894, Sir William Preece delivered a paper to the Royal Institution in London on electric signalling without wires.

The first practical radio transmitters and receivers invented in 1894–1895 by Guglielmo Marconi used radiotelegraphy. [5] It continued to be the only type of radio transmission during the first few decades of radio, called the "wireless telegraphy era" up until World War I , when the development of amplitude modulation (AM) radiotelephony ...

British Post Office engineers inspect Guglielmo Marconi's wireless telegraphy (radio) equipment in 1897. In 1894, the young Italian inventor Guglielmo Marconi began working on the idea of building long-distance a wireless transmission systems based on the use of Hertzian waves (radio waves), a line of inquiry that he noted other inventors did ...
The monopole antenna was invented in 1895 and patented in 1896 [7] by radio pioneer Guglielmo Marconi during his historic first experiments in radio communication. He began by using dipole antennas invented by Heinrich Hertz consisting of two identical horizontal wires ending in metal plates. He found by experiment that if instead of the dipole ...
