mauerbild (gelb) comes from the collection of Lady Noel E. Norton (1891-1972), a leading British collector and dealer in contemporary art from the 1930s until her death in 1972, who usually went by the nickname of 'Peter' Norton. The wife of a British ambassador (Sir Clifford Norton), Peter Norton was a passionate supporter of modern art, and made close friendships with a number of major artists through her long collecting career - from Paul Klee, Wassily Kandinsky, and Fernand Leger in her early years to Henry Moore, John Craxton, Nico Ghika and Yves Klein in her later years. She fell under the spell of the Bauhaus after meeting two of its members during a skiing holiday in Austria in the 1920s, and went on to became a close friend of Walter Gropius and a lifelong friend of Herbert Bayer. In 1936 with the help of Roland Penrose she opened the London Gallery in Cork Street, a high profile modern art gallery. There she works by Klee, Kandinsky, Leger, Magritte, Ernst, and Moore, among others. During World War II, her husband's diplomatic career took her away from London, so she handed the gallery over to E.L.T. Mesens. She nevertheless continued to support, collect and encourage artists all her life. She was a founder member of the ICA (Institute for Contemporary Arts) in London, and also remained a close friend to Herbert Bayer, even after he had moved to America. He gave her this painting as a gift. He gave a similar painting from that period to Walter Gropius (now in the Gropius House, Lincoln, Massachusetts)
