Physicist Oliver Lodge made several important technological contributions,
most notably his advancement of wireless telegraphy.
Lodge’s invention of wireless telegraphy stemmed from his research into
electromagnetic waves, and his patent of 1898 outlined a device that could
“transmit messages across space” between people in various locations. He
postulated that different stations could send and receive signals at
different frequencies, thus avoiding any interference between the stations.
His device achieved this by producing and transmitting a series of electric
oscillations and pulses—excited at a certain frequency— from a sending
station. The receiving station would be outfitted with an electric relay or
other such device that could capture the oscillation at its particular
He also advanced the motor vehicle industry by designing the Lodge Igniter,
an electric spark ignition for engines, an early form of spark plugs.
Lodge’s sons founded a company in the early 20th century to produce and
market the Lodge Igniter.
Born in Stokes-on-Trent, England Lodge earned his Bachelor of Science
degree from the University of London in 1875. He was knighted by King
Edward VII in 1902.
