THE DEPARTMENT OF MATHEMATICS
WHEN the seven young men who constituted the first student body came to Ann Arbor in the fall of 1841 to enter the newly organized University of Michigan, one of the two professors who welcomed them was the Reverend George Palmer Williams (Vermont '25, LL.D. Kenyon '49), Professor of Mathematics. To this year may therefore be assigned the birth of the Department of Mathematics.
Professor Williams, who was thirty-nine years old at that time, had had a varied teaching experience as principal of the preparatory school at Kenyon College, Ohio, for four years, and as a teacher of ancient languages in Western University of Pennsylvania and at Kenyon College for six years. He came to Ann Arbor from Pontiac, where he had been principal of the University's Pontiac branch since 1837 (see Part I: Branches) . When the first class graduated in 1845 Professor Williams, as President of the Faculty, gave the members their diplomas.
The history of the Department of Mathematics may be divided into four periods, the first extending from the entrance of the first class in 1841 to the appointment of Edward Olney in 1863, the second to the death of Professor Olney in 1887, the third to the death of Professor Beman in 1922, and the fourth to the present time.
The first period, 1841-63. — For a number of years after 1843 George P. Williams was listed in the annual Catalogue as Professor of Natural Philosophy and Mathematics. The total enrollment in the 1840's was so small that he was able to conduct all of the classes in both of these subjects, but as the University attracted more students it became necessary that his burden of teaching should be divided. Two professorships were formed from his chair in 1854, and his title was changed to Professor of Mathematics. In 1854-55 there were sixty-three freshmen — almost as many students as were in the other three classes combined. The following year Williams was assisted in mathematics by Alexander Winchell, then Professor of Natural History, and William G. Peck, Professor of Physics and Civil Engineering. In May, 1856, William Petit Trowbridge (U. S. Mil. Acad. '48, Ph.D. hon. Princeton '79, LL.D. Michigan '87) was also appointed Professor of Mathematics, but he served for only one year, and later had a distinguished career in engineering. One of the University's own graduates, John Emory Clark ('56, A.M. '59), was Assistant Professor of Mathematics for the following two years. During the remaining four years of the period Williams was assisted by James Craig Watson ('57, Ph.D. Leipzig '70, LL.D. Columbia '77). Watson, a gifted mathematician, was only twenty-one years old when he became Instructor in Mathematics and temporary Professor of Astronomy in 1859. He later brought fame to Michigan as Professor of Astronomy and Director of the Detroit Observatory (see Part III: Department of Astronomy) .
In this early period the work in mathematics included algebra and geometry in the freshman year, and plane and spherical trigonometry and some analytical geometry and calculus in the sophomore year. The books used, Davies' translations of Bourdon's Algebra and Legendre's Geometry, Davies and Loomis' Trigonometry, Loomis' Analytical Geometry, and Loomis' Differential and Integral Calculus, give some idea of the ground covered in the early courses.
