John Doe

The average person. This appellation actually dates from the thirteenth century, when it was used in legal documents to disguise the identity of witnesses; the tenant plaintiff was called John Doe and the landlord defendant Richard Roe. In the nineteenth century the name acquired the present meaning of ordinary person. A book, The O’Hara Family (1825), included “Tales, Containing . . . John Doe,” and almost a century later a movie starring Gary Cooper was entitled Meet John Doe (1941). Similar appellations include Joe Blow, first recorded in 1867; Joe Doakes, from the 1920s; and John Q. Public, coined by the writer William Allen White in 1937. John Doe has outlived them all.
