Roger Eliot Fry was an English painter and critic, and a member of the Bloomsbury Group. Establishing his reputation as a scholar of the Old Masters, he became an advocate of more recent developments in French painting, to which he gave the name Post-Impressionism. He was the first figure to raise public awareness of modern art in Britain, and emphasised the formal properties of paintings over the "associated ideas" conjured in the viewer by their representational content. He was described by the art historian Kenneth Clark as "incomparably the greatest influence on taste since Ruskin ... In so far as taste can be changed by one man, it was changed by Roger Fry". The taste Fry influenced was primarily that of the Anglophone world, and his success lay largely in alerting an educated public to a compelling version of recent artistic developments of the Parisian avant-garde.

John McTaggart Ellis McTaggart was an English idealist metaphysician. For most of his life McTaggart was a fellow and lecturer in philosophy at Trinity College, Cambridge. He was an exponent of the philosophy of Georg Wilhelm Friedrich Hegel and among the most notable of the British idealists. McTaggart is known for "The Unreality of Time" (1908), in which he argues that time is unreal. The work has been widely discussed through the 20th century and into the 21st.
