1877: Thomas Edison suggests using the word hello as a telephone greeting. The idea catches on.

Edison invented a lot of things, for sure, but one thing he didn't invent was the telephone. The brass ring for that one goes to Alexander Graham Bell, although Elisha Gray filed his patent for a similar device the same day. But they never called it Ma Gray, did they?

Edison's contribution to the "improvement in telegraphy" was giving us the salutation now used the world over, in one form or another. Bell's famous first words spoken over what we now call the telephone – "Mr. Watson, come here. I want to see you." – were delivered without any greeting at all.

When he did weigh in on the subject, Bell proposed using "ahoy, ahoy," the age-old seafarer's hail. And, in fact, ahoy was the first greeting used, until Edison suggested hello.

At the time, the phone was conceived of as a business machine that would connect two offices with a permanently open line. Some people toyed with the idea of an alarm bell at each end to alert one office that the other office wanted to speak. On Aug. 15, 1877, Edison wrote to a friend who was setting up a phone system in Pittsburgh: "I don't think we shall need a call bell as Hello! can be heard 10 to 20 feet away. What do you think?"

Contrary to some accounts, Edison did not coin the word. Halloo and variants had been used for ages to urge on hunting hounds and to shout to people at a distance. Edison was tinkering with a prototype phonograph in 1877 and used a shouted halloo! for testing. Early gramophones and telephones alike had pretty low signal-to-noise ratios.

Hello itself turns up in a number of places prior to 1877, including Mark Twain's travelogue, Roughing It, published four years before Bell called Mr. Watson. Earlier references to the word also exist, one dating back to at least 1826.

In any case, hello caught on quickly and entered the dictionary in 1883. And when was the last time you had to look up that spelling?
