Benjamin Thompson, Count Rumford, was-as Nicholas Delbanco writes-"world famous in his lifetime," yet now he has been "almost wholly forgotten." Like Delbanco himself, Sally Ormsby Thompson Robinson-the narrator of this novel and the Count's fictional, last-surviving relative-is "haunted" by one of history's most fascinating and remarkable figures. On par with Thomas Jefferson and Benjamin Franklin, Count Rumford was, among many other things, a politician, a spy, a philanthropist, and above all, a scientist. Based on countless historical documents, including letters and essays by Thompson himself, The Count of Concord brings to life the remarkable career of Benjamin Thompson, Count Rumford.
