Arnold Emch
Arnold Frederick Emch (24 March 1871 in Hessigkofen, Switzerland[1]–1959) was a Swiss-American mathematician, known for his work on the inscribed square problem.
After studying at ETH Zurich from 1890 to 1893, Emch traveled to America,[1] and received his Ph.D. in 1895 at the University of Kansas under the supervision of Henry Byron Newson.[2][3] In the late 1890s until 1905, he was an assistant professor of graphic mathematics in the school of engineering at the Kansas State Agricultural College (now Kansas State University).[4] In 1905, Emch became a professor of mathematics at the Kantonsschule in Solothurn, Switzerland.[5] In 1908, Emch gave a lecture at the International Congress of Mathematicians in Rome.[5] From 1911 to 1939, he was a professor at the University of Illinois Urbana-Champaign.[6]
His wife was Hilda Walters Emch and they had two sons, Walter Emch and Arnold Frederick Emch, a well-known management consultant.[7]
