Petts Wood is a suburb of South East London and is a part of the London Borough of Bromley (formerly in Kent). The name appeared first in 1577 as "the wood of the Pett family", who were shipbuilders and leased the wood as a source of timbers. William Willett, a campaigner for daylight saving time, lived in nearby Chislehurst for most of his life, and is commemorated by a memorial sundial in the wood.
