John Nash had no formal art training, but was encouraged by his brother to develop his abilities as a draughtsman. His early work was in watercolour and included Biblical scenes, comic drawings and landscapes. A joint exhibition with Paul at the Dorien Leigh Gallery, London, in 1913 was successful, and John was invited to become a founder-member of the London Group in 1914. He was an important influence on the work of the artist Dora Carrington (with whom he was in love), and some of her works have been mistaken for his in the past.
