Nathan Altshiller Court (January 22, 1881 – July 20, 1968) was a Polish–American mathematician. He was a geometer and the author of the popular book College Geometry,[1] who spent most of his career at the University of Oklahoma.
Immediately afterward he moved to New York City, anglicizing his name to Nathan Altshiller.[4][5] Though he could not read or write in English when he arrived, within weeks he began lecturing in advanced mathematics at Columbia University,[4] and at the beginning of the next semester he was hired as a mathematics instructor teaching evening classes while doing his graduate work in Mathematics and Astronomy during the day.[6] In 1912 he married Sophie Ravitch, whom he had known in Warsaw.[4] He left New York in 1913, teaching for two years at the University of Washington in Seattle where his son Arnold was born in 1914, and for two years at the University of Colorado.[4]
In 1916 he moved to the University of Oklahoma, where he remained for the rest of his career.[4][7] In 1919, he became a U.S. citizen and changed his last name to Court, keeping Altshiller as a middle name.[8][5] The first edition of his best known book, College Geometry, a university-level textbook in synthetic geometry, was published in 1925.[9] In 1935 he published the solid geometry textbook Modern Pure Solid Geometry[10] and became a full professor at the University of Oklahoma. He continued teaching there until his retirement in 1951. College Geometry was continually in print without revision for over 25 years, but a revised edition was published in 1952.[5] A collection of his essays, Mathematics in Fun and in Earnest, was published in 1958.[11]
In his recognition, the Nathan A. Court Award was established by the OU Department of Mathematics, given to an outstanding freshman or sophomore math major.[12]
