Henry Soskin, better known as Henry Lincoln, was a British author, television presenter, scriptwriter, and actor. He co-wrote three Doctor Who multi-part serials in the 1960s, and — starting in the 1970s — inspired three Chronicle BBC Two documentaries on the alleged mysteries surrounding the French village of Rennes-le-Château — and, from the 1980s, co-authored and authored a series of books of which The Holy Blood and the Holy Grail was the most popular, becoming the inspiration for Dan Brown's 2003 best-selling novel, The Da Vinci Code. He was the last living person to have written for Doctor Who in the 1960s.

Chronicle is a British television programme that was shown monthly and then fortnightly on BBC Two from 18 June 1966 until its last broadcast on 29 May 1991. Chronicle focused on popular archaeology and related subjects, and was considered an influential programme and a landmark in early television presentation of archaeology. The programme was commissioned by David Attenborough in 1966, and was produced by the Archaeological and Historical Unit headed by Paul Johnstone and later edited by Bruce Norman. Among the presenters of the programme were Magnus Magnusson, Colin Renfrew, David Drew, and John Julius Norwich.
