Dennis Miller Bunker (* November 6, 1861 in New York, N.Y.; December 28, 1890 in Boston, Massachusetts) was an American Impressionist painter.
At the age of 17 Bunker became a pupil of William Merritt Chase in 1878. With Chase's recommendation he moved to Jean-Léon Gérôme's studio in Paris in 1881 for almost four years.
In the autumn of 1885 Bunker returned to the USA and settled in Boston, Mass. In the same year he was appointed lecturer for painting at the "Cowles School of Arts" in Boston, Mass. He taught there until 1890 and influenced many students with his impressionistic style. One of the most important of these is Isabella Stewart Gardener, whose palace "Feway Court" together with her art collection was continued as the Isabella Stewart Gardner Museum after her death in 1924. But painters like William McGregor Paxton also owe much to Bunker.
Bunker only interrupted his teaching activities at the Cowles School of Arts in the summer of 1888, when he painted plein air landscapes together with John Singer Sargent in Calcott, Salop (GB). From this time on Bunker's painting style became more and more relaxed, although the influence of his teacher Gérôme with his strict accuracy is still recognizable.
At the age of 29, the first American impressionist Dennis Miller Bunker died of an untreated flu on 28 December 1890 in Boston, Massachusetts.
