McEvoy studied at the Slade School with Orpen and Augustus John, and had the reputation for a fine technical skill in oils, learnt from study with Whistler. There is a contrast between his earlier, solidly painted portraits, and his later blurred and sketchy handling of paint. The portrait of W A Jowitt (1885-1957) is at a mid point between these styles. Jowitt was then a young barrister, and later became Lord Chancellor under Atlee’s 1945 Government. He was also Chairman of the Trustees of the Tate Gallery.
