James Wickes Taylor (1819-1893) served as a special agent of the U.S. Treasury Department (1859–69), secret agent of the U.S. State Department in Canada (1870), and U.S. consul at Winnipeg (1870–93). The collection reveals Taylor’s interest in and influence on the economic development of Canada and the American Northwest, including his efforts to promote commerce between the two countries and his activities as a promoter of U.S. railroad interests. The papers include the official and private correspondence (1834–1957) of Taylor, documenting his career. After 1893 the papers consist largely of the correspondence of James Taylor Dunn that relates to his research (1930–50) on his grandfather.
