The picture in situ
Thomas Wilmer Dewing was born in Newton Lower Falls, Massachusetts in 1851. He studied at the Académie Julian in Paris, and later moved to New York. In 1897 he was one of the Ten American Painters who resigned from the Society of American Artists in protest at what they considered increasing commercialisation of that group's exhibitions. Ironically, the Society had itself broken away from the National Academey of Design twenty years previously. The group, who became just known as simply The Ten, painted their impressionist pictures for twenty years before the deaths of the members broke it up.
Dewing was very much a tonalist, an American movement whose most well known exponent was Whistler, who used the characteristic limited palette and misty style on figures, usually female, in cool interiors. He died in 1938.
