That Sickert had a defining influence on the development of Modern British painting is not in question. He spent time at the Slade and then as an assistant to Whistler. He knew Degas. Sickert was a friend and painting companion to Winston Churchill.
Sickert's approach was very confident and in a sense egocentric. When compared to many other painters, there is a heightened sense of a unique perspective. He paointed in his studio rather than en plen air and concentrated on the grime and mess of life.
"The plastic arts are gross arts, dealing joyousely with gross material facts." Walter Richard Sickert.
