Hans Wilhelm Eduard Schwerdtfeger FRSC (9 December 1902 – 26 June 1990) was a German-Canadian-Australian mathematician who worked in Galois theory, matrix theory, theory of groups and their geometries, and complex analysis.
"In 1962 he published Geometry of Complex Numbers: Circle Geometry, Möbius Transformations, Non-Euclidean Geometry which: ... should be in every library, and every expert in classical function theory should be familiar with this material. The author has performed a distinct service by making this material so conveniently accessible in a single book.
