Miyamoto, Sadaichi, and Carl L. A. Schmidt. The Conductivities of Aspartic Acid and of Glutamic Acid and Certain of their Salts and the Influence of Temperature Thereon, 1932, an original scientific paper documenting Miyamoto's participation in biochemical research at the University of California during a period of severe federal discrimination against Japanese immigration and Asian naturalization. The study examines the electrical conductivity of aspartic acid, glutamic acid, and selected salts under changing temperatures, contributing experimental data to the developing physical chemistry of amino acids and proteins. Miyamoto also collaborated with Schmidt on related biochemical research, including a 1930 paper on compound amino acids and a 1933 study of conductivity and ion formation in proteins and amino acids, demonstrating that the present work formed part of a sustained research program rather than an isolated publication. Carl L. A. Schmidt was professor and chair of biochemistry at Berkeley and pursued extensive research into the physical chemistry of amino acids and proteins. Miyamoto, Sadaichi, and Carl L. A. Schmidt. The Conductivities of Aspartic Acid and of Glutamic Acid and Certain of their Salts and the Influence of Temperature Thereon. Berkeley: University of California Press, 1932. University of California Publications in Physiology, Vol. 8, No. 2, pp. 9-20. The paper presents experimental findings on the conductivity of two biologically significant amino acids and certain of their salts, examining temperature as a variable and supplying tabulated experimental data. Its technical content places the publication within an active Berkeley program investigating amino acids, proteins, electrolytes, and their physical properties under Schmidt's direction. The surviving publication is therefore both a discrete contribution to interwar biochemistry and documentary evidence of Miyamoto's work within a major American research university. The timing gives the publication an additional Asian American historical context. Eight years earlier, the Immigration Act of 1924 had established an exclusion provision for aliens deemed ineligible to citizenship that federal officials acknowledged affected Japanese immigrants in particular; contemporary Japanese diplomatic protests explicitly condemned the measure as racial discrimination. Miyamoto's appearance in University of California records concerning Japanese American individuals further connects his scientific career to the history of people of Japanese descent associated with the university. No specific physical defects are supplied; overall very good. A substantive scientific publication combining the history of interwar American biochemistry with evidence of a Japanese researcher's participation in University of California laboratory science amid the exclusionary racial policies of the early twentieth-century United States.…
