In 1786 Owen moved to London, where he was apprenticed to the coach painter
Charles Catton (1728–1798). This position was most likely arranged by his uncle, who was butler to the scholar and art theorist
Richard Payne Knight, who lived near Ludlow. It appears that Owen was drawn to figure painting from the outset, and after copying a portrait by Sir
Joshua Reynolds of the much admired actress
Mary Robinson (better known as 'Perdita'), he was sent on the recommendation of Reynolds to the
Royal Academy Schools in 1791. By 1794 Owen had moved out of his lodgings with Catton on Gate Street and into a new to studio at No.211
Piccadilly where he remained for two years before moving to No.5 Coventry Street,
Haymarket. It is whilst living here that he presumably came into contact with future wife Lener Leaf, whose father worked in Haymarket as a shoe maker. By 1797 Owen was working as a studio assistant to
John Hoppner, who by this point was struggling to keep up with the demand for copies of his portraits. Owen was clearly also experiencing some success in his own right, for in the same year he painted Lener, along with her younger sister, and exhibited the portrait at
Somerset House – the then location of Royal Academy exhibitions, receiving a great deal of praise and encouragement. Owen married Lener later that year on 2 December and their son William was born soon after. In 1800 Owen and his family moved to
Pimlico, although choosing to maintain his recently acquired studio at No.51
Leicester Square, next door to the house in which Sir Joshua Reynolds lived. This remained Owen's studio until he became too ill and moved out in 1818. The year 1797/8 was perhaps the most significant in Owen's career as a painter; in 1797 he painted the then Prime Minister
William Pitt the Younger which he exhibited the following year along with a portrait of the
Lord Chancellor Alexander Wedderburn. == Royal appointment ==
