John Commingers Ainsworth (1822-1893) was the major founder of the Oregon Steam Navigation (OSN) Company, the most powerful transportation monopoly in the Pacific Northwest. Ainsworth was also involved in a number of other ventures, including the Northern Pacific Railroad (NPRR) and various gold, silver and coal mining operations. The John Commingers Ainsworth Papers contain Ainsworth's diaries, autobiography, personal correspondence, photographs, and the business records of the Oregon Central Railroad, Oregon Steam Navigation Company, Northern Pacific Railroad Company, and various mining, building and shipping enterprises.
Clarence Leroy Andrews was an employee of the Interior Department Bureau of Education and Reindeer Service in Alaska in the 1920s. He focused on Eskimos and their use of reindeer herds, writing several books about Eskimo life in Alaska. He was especially concerned with corporations which exploited reindeer herds, and led a campaign in the 1930s to remove Carl Momen of Seattle from control of the reindeer industry. The C. L. Andrews papers consist largely of business and personal correspondence, published and unpublished manuscripts, and photographs. Important to the collection are the W. T. Lopp files that relate to education in Alaska and the reindeer service from 1908-1939.
