Sir William Nicholson's still-lifes are perhaps his best known type of work today as well as his woodcuts of Victorian types and characters. With his brother-in-law James Pryde (1866-1941) he helped significantly in the development of the poster. The two were known as the Beggarstaff Brothers.
The best places to see his work are the Tate in London and the Fitzwilliam in Cambridge.
Of course, the fame of his son, Ben Nicholson OM eclipsed him. His other
children were Nancy Nicholson and the architect Christopher 'Kit' Nicholson. Nancy Nicholson was the first wife of Robert Graves. His wife, Mabel Pryde (1871-1918), was also an artist. They married in 1893.
