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:
“Unless your baby becomes uncomfortable and tries to push away, don’t worry that you’re cuddling too much. That way, when she reaches adolescence and goes through a normal period of being terribly embarrassed even to be seen with you in public, you’ll have some memories to tide you over until she comes around again.”
—Lawrence Kutner (20th century)
