Thomas Dale Stewart (August 14, 1890 – February 6, 1958) was an American chemist.

He was born at Sumner, Washington, and received his Ph.D. degree in chemistry from University of California at Berkeley in 1916. After one year of research at University of Chicago under Julius Stieglitz, he returned to Berkeley as an instructor in the chemistry department, and became a professor there in 1935.

University of Chicago Private research university in Chicago, Illinois, United States

The University of Chicago is a private research university in Chicago, Illinois. The university is composed of an undergraduate college, various graduate programs and interdisciplinary committees organized into five academic research divisions and seven professional schools. Beyond the arts and sciences, Chicago is also well known for its professional schools, which include the Pritzker School of Medicine, the Booth School of Business, the Law School, the School of Social Service Administration, the Harris School of Public Policy Studies, the Divinity School and the Graham School of Continuing Liberal and Professional Studies. The university holds top-ten positions in various national and international rankings.

Julius Stieglitz was an American chemist of German Jewish origin. He was a teacher and organic chemist with a major interest in pharmaceutical and medicinal chemistry.

His early research was about the mechanism of electron conduction in metals. The collaborative work with Richard C. Tolman led to the discovery of Stewart–Tolman effect. Later he worked on acid-base equilibria of organic nitrogen compounds, as well as reaction kinetics.

Richard C. Tolman American physicist

Richard Chace Tolman was an American mathematical physicist and physical chemist who was an authority on statistical mechanics. He also made important contributions to theoretical cosmology in the years soon after Einstein's discovery of general relativity. He was a professor of physical chemistry and mathematical physics at the California Institute of Technology (Caltech).

The Stewart–Tolman effect is a phenomenon in electrodynamics caused by the finite mass of electrons in conducting metal, or, more generally, the finite mass of charge carriers in an electrical conductor.

George M. Stratton American psychologist

George Malcolm Stratton was an American psychologist who pioneered the study of perception in vision by wearing special glasses which inverted images up and down and left and right. He studied under one of the founders of modern psychology, Wilhelm Wundt, and started one of the first experimental psychology labs in America, at the University of California, Berkeley. Stratton's studies on binocular vision inspired many later studies on the subject. He was one of the initial members of the philosophy department at Berkeley, and the first chair of its psychology department. He also worked on sociology, focusing on international relations and peace. Stratton presided over the American Psychological Association in 1908, and was a member of the National Academy of Sciences. He wrote a book on experimental psychology and its methods and scope; published articles on the studies at his labs on perception, and on reviews of studies in the field; served on several psychological committees during and after World War I; and served as advisor to doctoral students who would go on to head psychology departments.
