In this masterful intellectual and cultural biography of Denman Ross (1853–1935), the American design theorist, educator, art collector, and painter who taught at Harvard for over 25 years, Marie Frank has produced a significant artistic resurrection. An important regional figure in Boston’s fine arts scene (he remains one of the largest single donors to the collections of the MFA to this day), Ross was a friend and colleague of Arthur Wesley Dow, Bernard Berenson, Jay Hambidge, and others. He gained national and international renown with his design theory, which ushered in a shift from John Ruskin’s romantic naturalism to the formalist aesthetic that characterizes modern art and architecture. Ross’s theory attracted artists, Arts and Crafts artisans, and architects, and helped shape architectural education, scholarship, and museum practices. This biography of an important intellectual figure is also a fascinating and illuminating guide to a pivotal point in American cultural history and a reminder of the days when Boston was America’s salon.
