Johann Radon (December 16, 1887–May 25, 1956) was a mathematician born in Litoměřice in Bohemia (now Czech Republic). He wrote a doctoral dissertation on calculus of variations in 1910, at the University of Vienna.
He is known for a number of lasting contributions. These include
- his part in the Radon-Nikodym theorem;
- the Radon measure concept of measure as linear functional;
- the Radon transform, in integral geometry, based on integration over hyperplanes — with application to tomography for scanners (see tomographic reconstruction);
- Radon's theorem;
- the Radon-Hurwitz numbers.de:Johann Radon
