Norman Wilkinson (24 November 1878 – 30 May 1971) was a British artist who usually worked in oils, watercolours and drypoint. He was primarily a marine painter, but also an illustrator, poster artist, and wartime camoufleur. Wilkinson invented dazzle painting to protect merchant shipping during the First World War. Background Wilkinson was born in Cambridge, England, and attended Berkhamsted School in Hertfordshire and St. Paul's Cathedral Choir School in London. His early artistic training occurred in the vicinity of Portsmouth and Cornwall, and at Southsea School of Art, where he was later a teacher as well. He also studied with seascape painter Louis Grier. While aged 21, he studied academic figure painting in Paris, but by then he was already interested in maritime subjects. Illustration career Wilkinson's career in illustration began in 1898, when his work was first accepted by The Illustrated London News, for which he then continued to work for many years, as well as for the Illustrated Mail. Throughout his life, he was a prolific poster artist, designing for the London and North Western Railway, the Southern Railway and the London Midland and Scottish Railway. It was mostly owing to his fascination with the sea that he travelled extensively to such locations as Spain, Germany, Italy, Malta, Greece, Aden, the Bahamas, the United States, Canada and Brazil. He also competed in the art competitions at the 1928 and 1948 Summer Olympics.

In April 1917, German submarines achieved unprecedented success in torpedo attacks on British ships, sinking nearly eight per day. In his autobiography, Wilkinson remembers the moment when, in a flash of insight, he arrived at what he thought would be a way to respond to the submarine threat. He decided that, since it was all but impossible to hide a ship on the ocean (if nothing else, the smoke from its smokestacks would give it away), a far more productive question would be: how can a ship be made to be more difficult to aim at from a distance through a periscope? In his own words, he decided that a ship should be painted "not for low visibility, but in such a way as to break
