Arthur Henry Knighton-Hammond was born at Arnold, Nottingham, England, the youngest son of a modest shopkeeper and his wife. Leaving school at the age of 11, he never gave up his determination to study art and become a painter. For some years he was obliged to limit his passion to evening classes at the Nottingham School of Art. His natural ability shone through and in 1900 he moved to London to make a living as an artist. Augustus John, noted for his harsh criticisms of his brother artists, exclaimed upon seeing one of Knighton-Hammond's numerous exhibitions in France, 'That man is the greatest English painter in watercolor of our time".
