Most material in this collection was generated by Trigg early in his career as an industrial research fellow at Mellon Institute, Pittsburgh, 1916-1920 and shortly thereafter. It includes laboratory notebooks; formal weekly reports (typewritten) on his investigations; correspondence with his industrial sponsors; a few personal letters and some correspondence relating to his interest in coffee processing; his patents and correspondence relating to them; clippings and reprints of technical articles on tea and coffee processing and culture, 1883-1963; U.S. patents relating to these subjects, 1834-1921; foreign patents--British, French and German--1855-1918. Pamphlets contain technical articles on coffee and related subjects, including U.S. Department of Agriculture and Canadian government publications. Trigg's personal file of more than 5000 4" x 6" cards (mainly hand-written, arranged chronologically) reflect his extensive reading of technical literature; they contain bibliographical data and Trigg's brief abstractions.
