Jack Butler Yeats (29 August 1871 – 28 March 1957) was an Irish artist.
He was born in London and died in Dublin.
Yeats's early style was that of an illustrator and almost a cartoonist (he produced the first cartoon strip version of Sherlock Holmes in 1894); he only began to work regularly in oils in 1906. His early pictures are simple lyrical depictions of landscapes and figures, predominantly from the west of Ireland (especially his boyhood home of Sligo). There is a certain element of Romanticism in this work, but it is grounded in fine observation and brilliant draughtsmanship.
Yeats won a medal at the 1924 Tailteann Games in painting.
Yeats's favourite subjects include the Irish landscape, horses, circus and travelling players. His early paintings and drawings are distinguished by an energetic simplicity of line and colour, his later paintings by an extremely vigorous and experimental treatment of often thickly applied paint. He frequently abandoned the brush altogether, applying paint in a variety of different ways, and was deeply interested in the expressive power of colour. Despite his position as the most important Irish artist of the twentieth century (and the first to sell for over £1 m), he took no pupils and allowed no one watch him work, so he remains a unique figure. The artist closest to him in style is his friend, the Austrian painter, Oskar Kokoschka.
Besides painting, Yeats had a significant interest in theatre and in literature. He designed sets for the Abbey Theatre, but three of his own plays were also produced there. He wrote novels in a stream of consciousness style that Joyce acknowledged, and also many essays. His literary works include The Careless Flower, The Amaranthers (much admired by Beckett), and The Charmed Life. Yeats's paintings usually bear poetic and evocative titles. He was the youngest son of Irish portraitist John Butler Yeats, and the brother of the Nobel Prize winning poet William Butler Yeats, both of whom fully acknowledged all his talents. Indeed, his father recognized that Jack was a far better painter than he, and also believed that 'some day I will be remembered as the father of a great poet, and the poet is Jack'. Yeats was married to the painter Mary Cottenham White ('Cottie') in 1894 and elected a member of the Royal Hibernian Academy in 1916.
