George Stubbs (25 August 1724 – 10 July 1806) was an English painter, best known for his paintings of horses. Self-trained, Stubbs learnt his skills independently from other great artists of the 18th century such as Reynolds and Gainsborough. Stubbs' output includes history paintings, but his greatest skill was in painting animals, perhaps influenced by his love and study of anatomy. His series of paintings on the theme of a lion attacking a horse are early and significant examples of the Romantic movement that emerged in the late 18th century. He enjoyed royal patronage. His painting, Whistlejacket hangs in the National Gallery, London.
