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:
“Of all the barbarous middle ages, that
Which is most barbarous is the middle age
Of man! it is—I really scarce know what;
But when we hover between fool and sage,
And don’t know justly what we would be at—
A period something like a printed page,
Black letter upon foolscap, while our hair
Grows grizzled, and we are not what we were.”
—George Gordon Noel Byron (1788–1824)
