George Bruce Halsted

George Bruce Halsted (November 25, 1853 – March 16, 1922) was an American mathematician who explored foundations of geometry and introduced non-Euclidean geometry into the United States through his own work and his many important translations. Especially noteworthy were his translations and commentaries relating to non-Euclidean geometry, including works by Bolyai, Lobachevski, Saccheri, and Poincaré. He wrote an elementary geometry text, Rational Geometry, based on Hilbert's axioms, which was translated into French, German, and Japanese.

Life[edit]

Halsted was a tutor and instructor at Princeton University. He held a mathematical fellowship while a student at Princeton. Halsted was a fourth generation Princeton graduate, earning his Bachelor's degree in 1875 and his Master's in 1878. He went on to Johns Hopkins University where he was J. J. Sylvester's first student, receiving his Ph.D. in 1879. After graduation, Halsted served as an instructor in mathematics at Princeton until beginning his post at the University of Texas at Austin in 1884.

From 1884 to 1903, Halsted was a member of the University of Texas at Austin Department of Pure and Applied Mathematics, eventually becoming its chair. He taught mathematicians R. L. Moore and L. E. Dickson, among other students, who frequently joked that his primary criterion for the rationality of a geometric system was the simplicity of the terms in which it could express the closed space figure formed by the contours of his mustache. He explored the foundations of geometry and explored many alternatives to Euclid's development, culminating with his Rational Geometry. Halsted frequently contributed to the early American Mathematical Monthly. In one article[1] he championed the role of J. Bolyai in the development of non-Euclidean geometry and criticized C. F. Gauss. See also the letter from Robert Gauss to Felix Klein on 3 September 1912.

In 1903, Halsted was fired from UT Austin after having published several articles that criticized the university for having passed over R. L. Moore, at that time a young and promising mathematician whom Halsted hoped to have as an assistant, for an instructor post in favor of a well-connected but less qualified candidate with roots in the area.[2] He completed his teaching career at St. John's College, Annapolis; Kenyon College, Gambier, Ohio (1903-1906); and the Colorado State Teachers College, Greeley (1906-1914).
