George Clausen was born in London on 18 April 1852, the son of a decorative artist. From 1867 to 1873, he attended the design classes at the South Kensington Schools in London with great success. He then worked in the studio of Edwin Long RA, and subsequently in Paris under Bouguereau and Robert-Fleury. He was an admirer of the naturalism of the painter Jules Bastien-Lepage; about whom he wrote in 1888 and 1892.
Clausen became one of the foremost modern painters of landscape and of peasant life, influenced to a certain extent by the impressionists, with whom he shared the view that light is the real subject of landscape art. His pictures excel in rendering the appearance of things under flecking outdoor sunlight, or in the shady shelter of a barn or stable. His Girl at the Gate was acquired by the Chantrey Trustees and is now at the Tate Gallery. 
In 1895 he was elected an Associate of the Royal Academy, and a full Academician in 1906. As Professor of Painting at the Royal Academy he gave a memorable series of lectures to the students of the Schools, published as Six Lectures on Painting (1904) and Aims and Ideals in Art (1906).
Clausen was an official war artist during World War I. During the war his daughter's fiancé was killed; this event may have inspired his painting, Youth Mourning.
