The very best portrait artists gravitated to places where wealth and tradition were firmly in place -- Paris, London, New York City and Boston are prime examples. Joseph DeCamp (1858-1923) came from Cincinnati, studied under Frank Duveneck in Munich, but made his career in Boston. A short Wikipedia entry about him is here, and a more detailed biographical note can be found here. Apparently DeCamp painted many landscapes early in his career, but most of these were destroyed in a studio fire.
Besides painting commissioned portraits and teaching -- his main sources of professional income -- DeCamp created many paintings for his own purposes, many having beautiful women as the subject. They were often very good, as can be seen below.
My guess is that this was inspired by Vermeer; note the similar room arrangement.
