The British artist Adrian Hill coined the term "art therapy" in 1942. Hill, recovering from tuberculosis in a sanatorium, discovered the therapeutic benefits of drawing and painting while convalescing. He wrote that the value of art therapy lay in "completely engrossing the mind (as well as the fingers)…releasing the creative energy of the frequently inhibited patient", which enabled the patient to "build up a strong defence against his misfortunes". He suggested artistic work to his fellow patients. That began his art therapy work, which was documented in 1945 in his book, "Art Versus Illness".
