Who invented the alphabet we use today?

The history of writing in Britain begins with the Anglo-Saxons in the fifth century AD. With ties to Scandinavia and other North Seas cultures, ancient Anglo-Saxon writing, called futhorc, was a runic language. Flexible, new runes were routinely added such that, although it first appeared in England with 26 characters, by the time of its demise (by the 11th century AD), it had 33.

In the seventh century AD, the Latin alphabet introduced by Christian missionaries had begun to take hold. By 1011, a formal list of the Old English alphabet was made and included all of our present letters except J, U (or V) * and W. The ampersand and five uniquely English letters, designated ond, wynn, thorn, eth and ash, were included.
