This was the name of several dukes of Brittany, and Breton settlers introduced it to England after the Norman Conquest. Famous modern bearers include Alan Shepard (1923-1998), the first American in space and the fifth man to walk on the moon, and Alan Turing (1912-1954), a British mathematician and computer scientist.
Famous bearers include the British poet Alfred Tennyson (1809-1892), the Swedish inventor and Nobel Prize founder Alfred Nobel (1833-1896), and the British-American film director Alfred Hitchcock (1899-1980).
The name became regularly used in the Christian world due to the fame of Saint Anthony the Great, a 4th-century Egyptian hermit who founded Christian monasticism. Its popularity was reinforced in the Middle Ages by the 13th-century Saint Anthony of Padua, the patron saint of Portugal. It has been commonly (but incorrectly) associated with Greek ἄνθος (anthos) meaning "flower", which resulted in the addition of the h to this spelling in the 17th century.
Already beginning to rise on the American charts, this name got a further boost when child actor Brandon Cruz (1962-) debuted on the sitcom The Courtship of Eddie's Father in 1969 [1]. After cresting in popularity in the 1980s the name began to decline, but this was turned around by the arrival of the character Brandon Walsh on the television series Beverly Hills, 90210 in 1990 [1]. The name peaked in America ranked sixth in 1992.
In modern times, this name is borne by American fashion designer Calvin Klein (1942-), as well as one of the main characters from Bill Watterson's comic strip Calvin and Hobbes (published from 1985 to 1995).
This name also appears in the New Testament, belonging to man who sheltered Paul and Silas. In his case, it may represent a Hellenized form of a Hebrew name. It was not used in England until after the Protestant Reformation.
