George Bernard Shaw (c. 1890) --"The reasonable man adapts himself to the world: the unreasonable one persists to adapt the world to himself. Therefore all progress depends on the unreasonable man.” ― GBS, Man & Superman Photo by Sir Emery Walker, 1888. This is the only photo of him I've ever seen when he was young.
William Somerset Maugham (1874- 1965) was a British playwright, novelist and short story writer. He was among the most popular writers of his era and reputedly the highest paid author during the 1930s. He was a doctor whose first novel was so successful that he gave up medicine to write full time. He served as a doctor in WWI before being recruited into the British Intelligence Service. His works include 'Of Human Bondage' and 'The Razor's Edge'.
