Stylized blueprint portrait of Guglielmo Marconi

Guglielmo Marconi

1874 – 1937

Made wireless telegraphy a transatlantic reality.

The Italian inventor and entrepreneur who turned Hertz's laboratory waves into a communications industry, achieving the first transatlantic radio transmission in 1901 and winning the 1909 Nobel Prize.

His transatlantic feat made path loss and propagation engineering questions — the free-space-path-loss and radio-horizon tools here answer questions Marconi was first to pose commercially.
