Ernst Kötter (1859-1922) was a German mathematician.
Kötter graduated in 1884 from the University of Berlin under the supervision of Karl Weierstrass and Leopold Kronecker.
Kötter's treatise "Fundamentals of a purely geometrical theory of algebraic plane curves" gained the 1886 prize of the Berlin Royal Academy.[2]
In 1901, he published his report on "The development of synthetic geometry from Monge to Staudt (1847)";[3] it had been sent to the press as early as 1897, but completion was deferred by Kötter's appointment to Aachen University and a subsequent persisting illness.[4] He constructed a mobile wood model to illustrate the theorems of Dandelin spheres.[5] [6]
In a discussion with Schoenflies and Kötter, Hilbert reportedly uttered his famous quotation according to which points, lines, and planes in geometry could be named as well "tables, chairs, and beer mugs".[7]
