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.” 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. Linguists are divided as to when the symbol first appeared. Before The Keyboard Standardīefore 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. 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. 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.
In 1972, Ray Tomlinson sent the first electronic message, now known as email, using the symbol to indicate the location or institution of the email recipient.
