In 1873, Scottish physicist James Clerk Maxwell first advanced the
idea that there might be electromagnetic waves that were similar to
light waves, a startling concept to the scientists of his day.
About 13 years later, German physicist Heinrich Hertz demonstrated
in his laboratory that electromagnetic radiation did indeed exist.
But it was not until after Hertz's death that a young Italian named
Guglielmo Marconi got the idea for a practical communications
system based on Hertz's work. Marconi was surprised and
disappointed that the Italian government was not interested in his
newly discovered wireless communications system, and thus he took
his equipment to England. From that point on, the wireless became
identified with Britain. From these beginnings, wireless radio
became the basis of a revolution that has resulted in the satellite
communications of today. This history first looks at Marconi's
invention and then explores its many applications, including marine
radio, cellular telephones, police and military uses, television
and radar. Radio collecting is also discussed, and brief
biographies are provided for the major figures in the development
and use of the wireless.
