George Cumberland
George Cumberland was an English art collector, writer and poet. He was a lifelong friend and supporter of William Blake, and like him was an experimental printmaker. He was also an amateur watercolourist, and one of the earliest members of the Bristol School of artists. He made use of his wide circle of connections to help its other members, in particular assisting and influencing Edward Bird and Francis Danby.
Cumberland, whose father was also called George, was born in London in 1754. From 176985 he was an insurance clerk with the Royal Exchange Assurance Corporation. In 1772 he also attended the Royal Academy Schools and exhibited at the Academy in 1782 and 1783, but failed to be elected an Associate in 1784. He formed a low opinion of the Academy and attacked it in various essays.
