Edison became a telegraph operator after he saved three-year-old Jimmie MacKenzie from being struck by a runaway train. Jimmie's father, [[station agent]] J.U. MacKenzie of [[Mount Clemens, Michigan]], was so grateful that he trained Edison as a telegraph operator. Edison's first telegraphy job away from Port Huron was at Stratford Junction, [[Ontario]], on the [[Grand Trunk Railway]].<ref>Baldwin, page 37</ref>
