Origin and history of biography

1680s, "the histories of individual lives, as a branch of literature," probably from Medieval Latin biographia, from later Greek biographia "description of life" (which was not in classical Greek, bios alone being the word there for it), from Greek bios "life" (from PIE root *gwei- "to live") + graphia "record, account" (see -graphy).

The meaning "a history of some one person's life" is from 1791. The meaning "life course of any living being" is by 1854. No one-word verb form has become common; biographise/biographize (1800), biography (1844), biograph (1849) have been tried.
