Patrick Heron was born in Leeds and studied part time at the Slade School of Fine Art in London. Heron began to paint completely abstract works in the mid 1950s coinciding, more or less, with his permanent move from London to Cornwall and the first exhibition in Britain of American Expressionist painting shown at the Tate Gallery, London in 1956. Until then his work had been of interiors, figures and views through his studio window, inspired by Braque’s use of space an from but using a much brighter palette more in keeping with the interiors of Matisse.
