Cornelius Johnson or Cornelis Janssens van Ceulen (; also Cornelius Jonson van Ceulen, Cornelis Jansz. van Ceulen and many other variants) (bapt. 14 October 1593 – bur. 5 August 1661) was an English painter of portraits of Dutch or Flemish parentage. He was active in England, from at least 1618 to 1643, when he moved to Middelburg in the Netherlands to escape the English Civil War. Between 1646 and 1652 he lived in Amsterdam, before settling in Utrecht, where he died. Johnson painted many portraits of emerging new English gentry. His early portraits were panel paintings with "fictive" oval frames. His works can be found in major collections in the UK and overseas as well as in private collections in stately homes in Britain. He was an accomplished portrait painter, but lacked the flair of a master such as Van Dyck. His style varied considerably over his career, and he was able to assimilate new influences into his own style without any discordant effect. He was particularly accurate and detailed in his depiction of clothing. He was one of the few artists in England at this time who consistently signed and dated their work. Family life Johnson was born to Dutch or Flemish parents in London – his father had been a religious refugee from Antwerp, and his paternal grandfather had come from Cologne. He was baptised at the Dutch Church at Austin Friars much used by the Netherlandish community in London. He was the son of Johanna le Grand and Cornelius Johnson. He may have been trained in the Netherlands, possibly under Michiel Jansz. van Mierevelt. He was certainly influenced by other artists from the Netherlands, and his early works follow the design and mood of Dutch painters. He had returned to England by 1619 when he was a witness at the baptism of his nephew, Theodore Russell – Johnson' sister was married to Nicholas Russell of Bruges. He was active in England, from then until 1643. In the 1620s, he lived and had his studio in Blackfriars, London, as did Anthony van Dyck and Peter Oliver; it was within the boundaries of the City of London, but was a liberty and so avoided the monopoly in the City of members of the London painters' Guild. He married Elizabeth Beke of Colchester on 16 July 1622 at the Dutch church in London. Their son James (who presumably died young)
