Where
did the @ sign come from?

In
1972, Ray Tomlinson sent the first electronic message, now known
as e-mail, using the @ symbol to indicate the location or institution of the e-mail
recipient. Tomlinson, using a Model 33 Teletype device, understood that he needed to use
a symbol that would not appear in anyone's name so that there was no confusion.
The logical choice for Tomlinson was the "at sign," both because it was unlikely
to appear in anyone's name
and also because it represented the word "at," as in a
particular user is sitting @ this specific computer.

However,
before the symbol became a standard key on typewriter keyboards
in the 1880s and a standard on QWERTY keyboards in the 1940s, the @ sign had
a long if somewhat sketchy history of use throughout the world. Linguists are divided
as to when the symbol first appeared. Some argue that the symbol dates back to the 6th
or 7th centuries when Latin scribes adapted the symbol from the Latin word ad, meaning
at, to or toward. The scribes, in an attempt to simplify the amount of pen strokes they
were using, created the ligature (combination of two or more letters) by exaggerating
the upstroke of the letter "d" and curving it to the left over the
"a."

Other
linguists will argue that the @ sign is a more recent development,
appearing sometime in the 18th century as a symbol used in commerce to indicate
price per unit, as in 2 chickens @ 10 pence. While these theories are largely speculative,
in 2000 Giorgio Stabile, a professor of the history of science at La Sapienza University
in Italy, discovered some original 14th Century documents clearly marked with the @ sign
to indicate a
measure of quantity — the amphora, meaning jar. The amphora was a standard-sized terra cotta vessel used to carry wine and grain among merchants,
and, according to Stabile, the use of the @ symbol (the upper-case "A" embellished
in the typical Florentine script) in trade led to its contemporary meaning of "at
the price of."
While
in the English language, @ is referred to as the "at sign,"
other countries have different names for the symbol that is now so commonly used in e-mail transmissions
throughout the world. Many of these countries associate the symbol with either
food or animal names.
