Patents, ordnance pamphlets and diagrams, undated

The Minkler papers constitute a manuscript collection of one archival box containing thirteen folders which are divided into two series.

Series I consists of correspondence which is arranged chronologically in three folders covering the periods of 1911-1919, 1920-1928, and 1929-1952. This arrangement best reflects the progression of Minkler's career as well as the development of underwater weapons systems. The correspondence includes letters of career promotion and appointment, memoranda, commendations, patent communications, and personal items. Although most of the papers are of a routine nature, some of the signatures and initials are of prominant figures in American naval history. These individuals include Rear Admiral Ralph Earle, Rear Admiral Thomas C. Hart, Rear Admiral Charles B. McVay, Jr., Rear Admiral Theodore S. Wilkinson, and President Franklin D. Roosevelt, then Assistant Secretary of the Navy. Of particular note is a handwritten holograph by Captain W. Irving Chambers which provides a detailed critique of one of Minkler's experimental projects.

Series II, miscellany, is comprised of ten folders including newspaper clippings; patents, ordnance pamphlets, and diagrams; photographs; and a variety of other materials. The patents, ordnance pamphlets, and diagrams are of particular interest and value. These documents provide an in depth description of six of Minkler's inventions including the drifting mine, depth charge, horn mine, hydrostatic mine, torpedo recording mechanism, and magnetically controlled torpedo firing mechanism. The newspaper clippings are arranged chronologically revealing the development of Minkler's career as well as growing public respect for his accomplishments. The photographs illustrate various aspects of Minkler's life and career. They are topically arranged according to the following subjects: Naval Torpedo Station, Newport, R.I.; bombs and explosions; travel; personal life; and family camp. The last folder in the miscellany series contains a diversity of papers including blueprints for a small skiff, genealogical records, Minkler's calling card, his obituary, a European itinerary, published and unpublished articles, a commendation from the city of Newport, and a map of the city of Newport in 1955.
