Arnold Emch

Arnold F. Emch (24 March 1871 – 1959) was an American mathematician, known for his work on the inscribed square problem.

Emch received his Ph.D. in 1895 at the University of Kansas under the supervision of Henry Byron Newson.[1][2] 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).[3] In 1905 Emch became a professor of mathematics at the Kantonsschule in Solothurn, Switzerland.[4] In 1908 Emch gave a lecture at the International Congress of Mathematicians in Rome.[4] From 1911 to 1939 he was a professor at the University of Illinois Urbana-Champaign.[5]

His wife was Hilda Walters Emch (1875–1962)[6] and they had two sons, Walter Emch and Arnold Frederick Emch (1899–1989), a well-known management consultant.[7]

gollark: I'll just filter it to "these random items I put in" or something.
gollark: Unfortunately it doesn't seem able to specifically match "all damaged items" but this is better than nothing.
gollark: I never thought of using it with no item filter to just accept "all damaged stuff".
gollark: Oh, right, that's clever.
gollark: How do you configure "all damaged items"?
