In the United States, N. R. Danelian (who was the director of the 13-volume St. Lawrence Seaway Survey in the U.S. Department of Navigation (1932–63)), worked with the U.S. Secretary of State on Canadian-U.S. issues regarding the seaway, persevering through 15 years to gain passage by Congress of the Seaway Act. He later became president of the Great Lakes St. Lawrence Association to promote seaway development to benefit the American heartland. The seaway was heavily promoted by the Eisenhower administration, which had been concerned with a lack of US control.
