From The Arthur Conan Doyle Encyclopedia
George Scott (10 june 1873 - 14 january 1943) was a French illustrator, painter and poster designer. He was also known as George Scott de Plagnolles and Georges Bertin Scott.
Scott was specialized in military paintings and drawings. He was the student of the famous painter Édouard Detaille, also specialist in military topics. From his mentor he learned a virtuosity which enabled him to render minutely the expressions of the soldier in action as well as horses, weapons, and uniforms. He was known to exalt the Napoleonic saga. He was officially appointed Painter of the Army, and he covered World War I in France and in Balkans. He worked for the French magazine L'illustration and Lectures Pour Tous in 1908 where he did 9 illustrations of the novel The Tragedy of the Korosko written by Arthur Conan Doyle. As he often travelled to North Africa where he did several paintings, it probably inspired him for this novel.
