1910: By totting up the ages at which the Old Testament patriarchs begat their children, the 17th-century biblical scholar James Ussher arrived at a date for the Creation: 4004 B.C.

Despite the scientific advances of the 19th century, it didn’t disappear from Oxford University Press bibles until 1910.
