Died: 20 July 1937, Rome, Italy
Affiliation at the time of the award: Marconi Wireless Telegraph Co. Ltd., London, United Kingdom
Prize motivation: "in recognition of their contributions to the development of wireless telegraphy."
Prize share: 1/2
In the late 1880s a previously unknown type of radiation was discovered - radio waves. It was found to have the same nature as light, but with a greater wavelength. Various physicists and technicians investigated whether radio waves could be used to transmit signals. In 1895, Guglielmo Marconi used radio waves to transmit signals over a distance of several kilometers. He developed the technology in subsequent years to achieve greater range. The foundation for both wireless telegraphy and radio had been laid.
Their work and discoveries range from how cells adapt to changes in levels of oxygen to our ability to fight global poverty.
