Mid 17th century (as a term in geometry and physics): from Latin, literally 'domestic hearth'.
In Latin focus meant ‘hearth, fireplace’, and the optical sense of ‘the burning point of a lens’, the point at which rays meet after reflection or refraction, may have developed from this. It was first used in 1604 in Latin in this sense by the German astronomer Johannes Kepler ( 1571–1630). By the beginning of the 18th century the word had appeared in the writings of such eminent figures as the philosopher Thomas Hobbes ( 1588–1679), the scientist Robert Boyle ( 1627–91), and the mathematician and physicist Isaac Newton ( 1643–1727). The focus groups of modern marketing are much more recent, dating from the early 1960s. Latin focus became foyer in French, in the sense ‘hearth’. It came to be used in French for the ‘green-room’ in a theatre, and then for the area that the public could gather in during intervals, a sense first found in English in 1859. See also fuel
