Thomas Shaughnessy, 1st Baron Shaughnessy

Thomas George Shaughnessy, 1st Baron Shaughnessy, (6 October 1853 – 10 December 1923) was an American-Canadian railway administrator who rose from modest beginnings as a clerk and bookkeeper for the Milwaukee and St. Paul Railroad (a predecessor of the Chicago, Milwaukee, St. Paul and Pacific Railroad) to become the president of the Canadian Pacific Railway, serving in that capacity from 1899 to 1918. In recognition of his stewardship of the CPR and its contributions to the war effort during the Great War, Shaughnessy was elevated to the Peerage of the United Kingdom on 1 January 1916 as Baron Shaughnessy, of the City of Montreal in the Dominion of Canada and of Ashford in the County of Limerick.
