Hugo Hadwiger (1908 – 1981) was a Swiss mathematician. Year 1908 ( MCMVIII) was a Leap year starting on Wednesday (link will display the full calendar of the Gregorian calendar (or a Leap year Year 1981 ( MCMLXXXI) was a Common year starting on Thursday (link displays the 1981 Switzerland (English pronunciation; Schweiz Swiss German: Schwyz or Schwiiz Suisse Svizzera Svizra officially the Swiss Confederation A mathematician is a person whose primary area of study and research is the field of Mathematics. He is known for Hadwiger's theorem in integral geometry, and a number of conjectures. In Integral geometry (otherwise called geometric probability theory Hadwiger's theorem states that the space of "measures" (see below defined on Finite unions In Mathematics, the term integral geometry is used in two ways which although related imply different views of the content of the subject He also worked on a Swiss enhancement of the Enigma cipher machine, known as NEMA. The Enigma machine is any one of a family of related electro-mechanical Rotor machines used to generate Ciphers for the Encryption and decryption of In the History of cryptography, the NEMA (NEue MAschine ("new machine" also designated the T-D (Tasten-Druecker-Maschine ("key-stroke machine"
His 1957 book Vorlesungen über Inhalt, Oberflache und Isoperimetrie was foundational for the theory of Minkowski functionals, used in mathematical morphology. In Functional analysis, given a linear space X, a Minkowski functional is a device that uses the linear structure to introduce a topology on X. Mathematical morphology (MM is a theory and technique for the analysis and processing of geometrical structures based on Set theory, Lattice theory, Topology
