There is a claim that his father was a decorative artist, but this may be a misreading of the single known quote about Dobson Sr, by the antiquarian John Aubrey, which states that William senior assisted Francis Bacon with the designs of Verulam House but "he spending his estate upon women, necessity forced his son ... to be the most excellent painter that England hath yet bred".
[5][6] Dobson is believed to have had access to the Royal Collection and to have copied works by Titian and Anthony van Dyck, the court painter of King Charles I of England.
Little is known of Dobson's career in the 1630s, but when Van Dyck died in 1641, the opportunity arose for him to gain royal commissions from King Charles.
His portrait of the future Charles II as Prince of Wales at the age of around twelve is a notable baroque composition, and perhaps his finest work.
The 2011 anniversary of his birth was marked by exhibitions, a 'Dobson Trail' listing his paintings on a website, and a BBC television profile by Januszczak, The Lost Genius of British Art: William Dobson.
