Van der Waerden learned advanced mathematics at the University of Amsterdam and the University of Göttingen, from 1919 until 1926.
He was much influenced by Emmy Noether at Göttingen, Germany. Amsterdam awarded him a Ph.D. for a thesis on algebraic geometry, supervised by Hendrick de Vries.^{[1]} Göttingen awarded him the habilitation in 1928. In that year, at the age of 25, he accepted a professorship at the University of Groningen.

In his 27th year, van der Waerden published his Moderne Algebra, an influential two-volume treatise on abstract algebra, still cited, and perhaps the first treatise to treat the subject as a comprehensive whole. This work systematized an ample body of research by Emmy Noether, David Hilbert, Richard Dedekind, and Emil Artin. In the following year, 1931, he was appointed professor at the University of Leipzig.

During the rise of the Third Reich and through World War II, van der Waerden remained at Leipzig, and passed up opportunities to leave Nazi Germany for Princeton and Utrecht. However, he was critical of the Nazis and refused to give up his Dutch nationality, both of which led to difficulties for him.^{[2]}

Following the war, van der Waerden was repatriated to the Netherlands rather than returning to Leipzig (then under Soviet control), but struggled to find a position in the Dutch academic system, in part because his time in Germany made his politics suspect and in part due to Brouwer's opposition to Hilbert's school of mathematics. After a year visiting Johns Hopkins University and two years as a part-time professor, in 1950 van der Waerden filled the chair in mathematics at the University of Amsterdam.^{[3]} In 1951, he moved to the University of Zurich, where he spent the rest of his career, supervising more than 40 Ph.D. students.

Van der Waerden is mainly remembered for his work on abstract algebra. He also wrote on algebraic geometry, topology, number theory, geometry, combinatorics, analysis, probability and statistics, and quantum mechanics (he and Heisenberg had been colleagues at Leipzig). In his later years, he turned to the history of mathematics and science. His historical writings include *Ontwakende wetenschap* (1950), which was translated into English as *Science Awakening* (1954), *Sources of Quantum Mechanics* (1967), *Geometry and Algebra in Ancient Civilizations* (1983), and *A History of Algebra* (1985).

Van der Waerden has over 1000 academic descendants, most of them through three of his students, David van Dantzig (Ph.D. Groningen 1931),
Herbert Seifert (Ph.D. Leipzig 1932), and Hans Richter (Ph.D. Leipzig 1936, co-advised by Paul Koebe).^{[4]}

Alexander SoiferAlexander Soifer is a Russian-born American mathematician and mathematics author. His works include over 400 articles, and 13 books.

Soifer received his Ph.D. in 1973. Soifer has been a professor of mathematics at the University of Colorado since 1979. He was visiting fellow at Princeton University 2002–2004, and again 2006–2007. Soifer also teaches courses on art history and European cinema. His publications include 13 books and over 400 articles.

Every spring, Soifer, along with other mathematician colleagues, sponsors the Colorado Mathematical Olympiad (CMO) at the University of Colorado at Colorado Springs. Soifer compiles and writes most of the problems for the contest. The CMO was founded by Soifer on April 18, 1983 (http://olympiad.uccs.edu/).

In 1991 Soifer founded the research quarterly Geombinatorics, and publishes it with the Editorial Board, which includes Ronald L. Graham, Jaroslav Nešetřil, Branko Grünbaum, Heiko Harborth, Peter D. Johnson Jr., Geoffrey Exoo, and János Pach. Paul Erdős was also an editor. (http://geombina.uccs.edu/)

In July 2006 at the University of Cambridge, Alexander Soifer was presented with the Paul Erdős Award by the World Federation of National Mathematics Competitions.

Soifer is currently the President of the World Federation of National Mathematics Competitions (http://www.wfnmc.org/). Soifer's Erdős number is 1.

Soifer's current projects include new publications and new expanded editions through scientific publisher, Springer of previously published books, "Mathematics as Problem Solving," "How does one cut a triangle?," "Geometric Etudes in Combinatorial Mathematics," and "Colorado Mathematical Olympiad: The First Ten Years and Further Explorations." The latter aforementioned title is expected to be expanded to cover twenty years of the Colorado Mathematical Olympiad, which is currently in its 35th year running.

In recognition of 35 years of leadership, the judges and winners decided in 2018 to rename the Colorado Mathematical Olympiad to the Soifer Mathematical Olympiad.

Soifer is the father of four children, Mark Soifer, Julia Soifer, Isabelle Soifer and Leon Soifer.

Arthur Byron CobleArthur Byron Coble (November 3, 1878 – December 8, 1966) was an American mathematician. He did research on finite geometries and the group theory related to them, Cremona transformations associated with the Galois theory of equations, and the relations between hyperelliptic theta functions, irrational binary invariants, the Weddle surface and the Kummer surface. He was President of the American Mathematical Society from 1933 to 1934.

List of Leipzig University peopleThe following is a list of notable alumni and faculty of the University of Leipzig.

Moderne AlgebraModerne Algebra is a two-volume German textbook on graduate abstract algebra by Bartel Leendert van der Waerden (1930, 1931), originally based on lectures given by Emil Artin in 1926 and by Emmy Noether (1929) from 1924 to 1928. The English translation of 1949–1950 had the title Modern algebra, though a later, extensively revised edition in 1970 had the title Algebra.

The book was one of the first textbooks to use an abstract axiomatic approach to groups, rings, and fields, and was by far the most successful, becoming the standard reference for graduate algebra for several decades. It "had a tremendous impact, and is widely considered to be the major text on algebra in the twentieth century."In 1975 van der Waerden described the sources he drew upon to write the book.In 1997 Saunders Mac Lane recollected the book's influence:

Upon its publication it was soon clear that this was the way that algebra should be presented.

Its simple but austere style set the pattern for mathematical texts in other subjects, from Banach algebras to topological group theory.

[Van der Waerden's] two volumes on modern algebra ... dramatically changed the way algebra is now taught by providing a decisive example of a clear and perspicacious presentation. It is, in my view, the most influential text of algebra of the twentieth century.

Outline of combinatoricsCombinatorics is a branch of mathematics concerning the study of finite or countable discrete structures.

Ramsey theoryRamsey theory, named after the British mathematician and philosopher Frank P. Ramsey, is a branch of mathematics that studies the conditions under which order must appear. Problems in Ramsey theory typically ask a question of the form: "how many elements of some structure must there be to guarantee that a particular property will hold?" More specifically, Ron Graham describes Ramsey theory as a "branch of combinatorics".

Seleucus of SeleuciaSeleucus of Seleucia (Greek: Σέλευκος Seleukos; born c. 190 BC; fl. c. 150 BC) was a Hellenistic astronomer and philosopher. Coming from Seleucia on the Tigris, Mesopotamia, the capital of the Seleucid Empire, or, alternatively, Seleukia on the Erythraean Sea, he is best known as a proponent of heliocentrism and for his theory of the origin of tides.

Van der Waerden notationIn theoretical physics, van der Waerden notation refers to the usage of two-component spinors (Weyl spinors) in four spacetime dimensions. This is standard in twistor theory and supersymmetry. It is named after Bartel Leendert van der Waerden.

Van der Waerden testNamed after the Dutch mathematician Bartel Leendert van der Waerden, the Van der Waerden test is a statistical test that k population distribution functions are equal. The Van der Waerden test converts the ranks from a standard Kruskal-Wallis one-way analysis of variance to quantiles of the standard normal distribution (details given below). These are called normal scores and the test is computed from these normal scores.

The k population version of the test is an extension of the test for two populations published by Van der Waerden (1952,1953).

Wilbur KnorrWilbur Richard Knorr (August 29, 1945 – March 18, 1997) was an American historian of mathematics and a professor in the departments of philosophy and classics at Stanford University. He has been called "one of the most profound and certainly the most provocative historian of Greek mathematics" of the 20th century.
