Eugène Ehrhart
Eugène Ehrhart (29 April 1906 – 17 January 2000) was a French mathematician who in the 1960s introduced Ehrhart polynomials, which count the lattice points in a polytope In elementary geometry, a polytope is a geometric object with flat sides ('' faces''). Polytopes are the generalization of three-dimensional polyhedra to any number of dimensions. Polytopes may exist in any general number of dimensions as an ... with integral vertices, their reciprocity property, and their generalization to rational polytopes. Ehrhart received his high school diploma at the age of 22. He was a mathematics teacher in several high schools, and did mathematics research on his own time. He started publishing in mathematics in his 40s, and finished his PhD thesis at the age of 60.

Ehrhart Polynomial
In mathematics, an integral polytope has an associated Ehrhart polynomial that encodes the relationship between the volume of a polytope and the number of integer points the polytope contains. The theory of Ehrhart polynomials can be seen as a higher-dimensional generalization of Pick's theorem in the Euclidean plane. These polynomials are named after Eugène Ehrhart who introduced them in the 1960s. Definition Informally, if is a polytope, and is the polytope formed by expanding by a factor of in each dimension, then is the number of integer lattice points in . More formally, consider a lattice \mathcal in Euclidean space \R^n and a -dimensional polytope in \R^n with the property that all vertices of the polytope are points of the lattice. (A common example is \mathcal = \Z^n and a polytope for which all vertices have integer coordinates.) For any positive integer , let be the -fold dilation of (the polytope formed by multiplying each vertex coordinate, in a basis fo ...

Gustav Ehrhart
Gustav Ehrhart (21 December 1894 – 11 December 1971) was a German chemist. He synthesized the first fully synthetic opioid analgesic, methadone, together with Max Bockmühl. Education and professional positions Ehrhart studied chemistry at the University of Heidelberg, with a focus on organic chemistry. His studies were interrupted by the First World War. He served as an artillery officer. After the war he resumed his studies and was awarded a doctorate degree in 1922. One of his professors was Theodor Curtius. Ehrhart received the Victor-Meyer Award for his dissertation. In 1923 he started working for Hoechst AG. Two years later he became the deputy of Max Bockmühl, the head of the pharmaceutical research laboratories of the company. In 1949, after the Second World War, Erhardt succeeded Bockmühl as the head of the entire pharmaceutical research division of Hoechst AG. In 1951 he became a deputy member of the Board, and two years later a regular member of Hoechst AG's Boa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jakob Friedrich Ehrhart
Jakob Friedrich Ehrhart (4 November 1742, Holderbank, Aargau – 26 June 1795) was a German botanist, a pupil of Carl Linnaeus at Uppsala University, and later director of the Botanical Garden of Hannover, where he produced several major botanical works between 1780 and 1793. Ehrhart was the first Author (botany), author to use the rank of subspecies in botanical literature, and he published many subspecific names between 1780 and 1789. Ehrhart issued several exsiccata, exsiccatae, the first one ''Phytophylacium Ehrhartianum, continens plantas, quas in locis earum natalibus collegit et exsiccavit Fridericus Ehrhart'' (1780-1785).Triebel, D. & Scholz, P. 2001–2024 ''IndExs – Index of Exsiccatae''. Botanische Staatssammlung München: http://indexs.botanischestaatssammlung.de. – München, Germany. He was one of the first who prepared exsiccatae for selling them to colleagues, namely the series ''Arbores, frutices et suffrutices Linnaei quas in usum dendrophilorum collegit et exsic ...

Ehrhart Neubert
Ehrhart Neubert (2 August 1940 – 17 November 2024) was a German evangelical minister and theologian. During its final decade he emerged as an opponent of the East German one-party dictatorship, becoming a member of the League of Evangelical Churches in the German Democratic Republic (''Bund der Evangelischen Kirchen in der DDR''/BEK). Since the collapse of the East German political regime in 1989/90 he has participated prominently on committees and as an author seeking to understand and evaluate it.

Surnames From Given Names
In many societies, a surname, family name, or last name is the mostly hereditary portion of one's personal name that indicates one's family. It is typically combined with a given name to form the full name of a person, although several given names and surnames are possible in the full name. In modern times most surnames are hereditary, although in most countries a person has a right to change their name. Depending on culture, the surname may be placed either at the start of a person's name, or at the end. The number of surnames given to an individual also varies: in most cases it is just one, but in Portuguese-speaking countries and many Spanish-speaking countries, two surnames (one inherited from the mother and another from the father) are used for legal purposes. Depending on culture, not all members of a family unit are required to have identical surnames. In some countries, surnames are modified depending on gender and family membership status of a person.
