Ph.D. University of Chicago, Illinois, 1900
When the U.S. joined World War I, Bliss was one of many mathematicians who contributed his scientific expertise; he worked on ballistics, designed new firing tables for artillery, and lectured on navigation. He spent the last part of his career at the University of Chicago (1908 until his retirement). His main work was on the calculus of variations, and he also studied singularities of real transformations in the plane. Bliss was a member of the U.S. National Academy of Sciences.
