Guglielmo Marconi, 25 April 1874 – 20 July 1937) was an Italian electrical engineer, inventor, and fascist politician known for his creation of a practical radio wave-based wireless telegraph system.
This led to Marconi being largely credited as the inventor of radio and sharing the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy". His work laid the foundation for the development of radio, television, and all modern wireless communication systems.
Marconi did not attend school as a child and did not go on to formal higher education. Instead, he learned chemistry, mathematics, and physics at home from a series of private tutors hired by his parents. His family hired additional tutors for Marconi in the winter when they would leave Bologna for the warmer climate of Tuscany or Florence.
From youth, Marconi was interested in science and electricity. In the early 1890s, he began working on the idea of "wireless telegraphy" – i.e., the transmission of telegraph messages without connecting wires as used by the electric telegraph.
This was not a new idea; numerous investigators and inventors had been exploring wireless telegraph technologies and even building systems using electric conduction, electromagnetic induction and optical (light) signalling for over 50 years, but none had proved technically and commercially successful.
