Brattle Street in Cambridge, Massachusetts, called the "King's Highway" or "Tory Row" before the American Revolutionary War, is the site of many buildings of historical interest, including the modernist glass-and-concrete building that housed the Design Research store, and a Georgian mansion where George Washington and Henry Wadsworth Longfellow both lived, as well as John Vassall and his seven slaves including Darby Vassall. Samuel Atkins Eliot, writing in 1913 about the seven Colonial mansions of Brattle Street's "Tory Row," called the area "not only one of the most beautiful but also one of the most historic streets in America." "As a fashionable address it is doubtful if any other residential street in this country has enjoyed such long and uninterrupted prestige."
