The United States Coast Guard traces its origins to 1790, but was not officially named until 1915. At last there is one definitive volume describing its history on The Great Lakes from inception to the present. The author, Thomas P. Ostrom, served in the USCGR from 1961-69, and had basic and advanced training at the USCG Base, Alameda, California. He served subsequently in the Port Security Reserve Unit in Duluth, Minnesota, and participated in monthly and active duty assignments each summer, earning petty officer rank.
