Joseph N. Borglin was born in Minnesota on March 24, 1899, and earned his B. S. degree in chemical engineering from the University of Washington in 1924. From 1926 to his retirement in 1964, he was employed at the Hercules Powder Company. He specialized in research on terpenes and resin acids, and received over 120 patents for his work. The records consist of typescripts of two works by Borglin, TREATISE ON VINSOL RESIN, in 1943 and 1946 editions, and the two-volume edition of TREATISE ON ROSIN (1945). One of the chapters in the latter work is titled, "History and Manufacture of Naval Stores Products," and includes photos of the various work processes involved in extracting pitch and pine tar.
