appointed — James Andrew Nyswander (California '13, Ph.D. Chicago '24), George Yuri Rainich (Magister of Pure Mathematics, Kazan '13), and Raymond Louis Wilder (Brown '20, Ph.D. Texas '23). At the close of that year Markley became Professor Emeritus.
By resolution of the Regents in 1928 the Department of Mathematics in the College of Literature, Science, and the Arts and the Department of Mathematics in the College of Engineering were reunited under the chairmanship of Professor Glover. William Dowell Baten (Baylor '14, Ph.D. Michigan '29) was added as an instructor in the fall of 1928. Alexander Ziwet died on November 18, 1928, and Joseph L. Markley a little more than a year later, April 19, 1930. In 1929-30 two new assistant professors were appointed — William Leake Ayres (Southwestern '23, Ph.D. Pennsylvania '27) and Arthur Herbert Copeland (Amherst '21, Ph.D. Harvard '26). Also in that year Assistant Professor Shohat resigned.
Professor Glover was absent on leave during the two years 1930-32 in order to devote his time to the Teachers Insurance and Annuity Association, of which he was president, and Field was Acting Chairman of the department. Glover, upon his retirement from the chairmanship in the fall of 1934, was named Edward Olney Professor of Mathematics, a distinction conferred in recognition of his services to the University and to the department. T. H. Hildebrandt was designated as his successor. At the beginning of the year the department lost Assistant Professor Denton.
During the five years 1935-40 the following changes in the staff took place: Glover and Ford retired and were named professors emeritus, and Associate Professor Menge and Assistant Professor Baten left the University; Carver, Wilder, and Rainich were appointed to full professorships; Copeland and Churchill became associate professors; and Edwin Wilkinson Miller ('26, Ph.D. '30), Sumner Byron Myers (Harvard '29, Ph.D. ibid. '32), and Paul Sumner Dwyer (Allegheny '21, Ph.D. Michigan '36) were appointed assistant professors. At the close of the academic year 1939-40 the Department of Mathematics had a staff of nine professors, seven associate professors, seven assistant professors, and eleven instructors.
When the most recent period in the history of the department began in 1922, all the main branches of mathematics were represented by courses. The additions to the staff made possible extension in the fields of topology, differential geometry and relativity, modern algebraic theory, and probability. The number and variety of graduate courses has been increased, and the use of the seminar method has been extended. The most striking characteristic of this period has been the emphasis placed upon research and graduate work. This is reflected in the number of doctor's theses written. Although only eleven doctor's degrees had been conferred up to 1922, seventy-four were conferred in the eighteen succeeding years. Increased interest and activity in mathematical research on the part of members of the staff have naturally accompanied this growth. Other activities of the department have not been neglected. Not only is there adequate provision for those whose interest is along mathematical lines, but the increased need of mathematics in other fields has called for expansion in courses of interest primarily to engineering students and in courses in actuarial science and in mathematical statistics and their applications. The Department of Mathematics is growing not only by furthering its own interests but also by serving the the needs of other departments.
