Manson’s work is characterised by small impasto touches of colour. Creating richly toned pleasing depictions of naturalistic objects and scenes. He also worked at the Tate Gallery for 25 years and served as its director from 1930-1938. He became a member of the Camden Town Group through his lifelong friendship with the impressionist painter Lucien Pissarro. Dedicated to the Impressionist technique his painting was more distanced in style than other members of the group.
