Period 1838-1897
Wireless telegraphy dates as far back as Faraday in the early 19th century, when it was discovered that radio waves could be used to send telegraph messages. After James Clerk Maxwell had predicted the existence of electromagnetic waves, and had shown that their speed of propagation is identical with that of light, it required, in reality, very little to demonstrate by experiment the existence of such waves.

Famous quotes containing the word period:
“Intellectual life is international. Only a period of discouragement, an age that has given up on itself, that wants to “preserve,” that has been driven onto the defensive, can be intellectually nationalist. Such a period is essentially “conservative.” A person who has progress in his heart is international.”
—Robert Musil (1880–1942)
