A German mathematician connected to the Vienna Circle, known for his work in topology, particularly in the development of Reidemeister moves, a set of algebraic operations used to simplify knot diagrams.
Kurt Reidemeister, a German mathematician, is renowned for his groundbreaking work in combinatorial group theory, geometric group theory, and the foundations of geometry. His most notable contribution is the development of knot theory, which has far-reaching implications in mathematics, physics, and computer science.
Born on October 13, 1893, in Braunschweig, Germany, Reidemeister was the brother of Marie Neurath. He began his academic journey in 1912, studying in Freiburg, Munich, Marburg, and Göttingen. In 1920, he obtained his Staatsexamen (master's degree) in mathematics, philosophy, physics, chemistry, and geology. A year later, he earned his doctorate in algebraic number theory from the University of Hamburg under the supervision of Erich Hecke.
Reidemeister's interest in differential geometry led him to edit Wilhelm Blaschke's second volume on the topic. He also made a significant contribution to the Jena DMV conference in September 1921. In 1922, he became an assistant professor at the University of Vienna, where he was introduced to the work of Wilhelm Wirtinger on knot theory. During this period, he also became closely connected to Hans Hahn and the Vienna Circle.
Some of his notable works include:
These works showcased his expertise in combinatorial group theory, combinatorial topology, and geometric group theory, cementing his position as a prominent mathematician of his time.
In 1933, Reidemeister was dismissed from his position at the University of Königsberg due to his perceived "politically unsound" views by the Nazi regime. Despite this setback, he continued to thrive, securing a chair at the University of Marburg in 1934. He later visited the Princeton Institute for Advanced Study in 1948-1950 and eventually became a professor at Göttingen University in 1955, where he remained until his emeritation.
Reidemeister's work has had a profound impact on the development of modern mathematics, influencing notable mathematicians such as Wilhelm Wirtinger and John Conway. His contributions to knot theory have far-reaching implications in physics, computer science, and biology, making him a pioneer in the field.
As a testament to his enduring legacy, Reidemeister's work continues to inspire new generations of mathematicians, ensuring his place as one of the most significant mathematicians of the 20th century.

Born in 1882
Developed a visual approach to presenting complex social and economic data, creating a system of pictograms to convey information in a clear and concise manner.
Born in 1905
A key figure in the development of logical positivism, they sought to establish a scientific philosophy that emphasized empirical evidence and logical reasoning. Their work significantly influenced the philosophy of science and epistemology.
Born in 1884
A pioneer in logical positivism, he merged philosophy and science to understand the nature of reality, and his work significantly influenced the development of modern philosophy of science.
Born in 1891
A key figure in the Vienna Circle, this philosopher developed logical positivism, a movement that sought to apply scientific methods to philosophy, and made significant contributions to the philosophy of science and probability theory.
Born in 1891
A historian and philosopher of science who contributed to the development of the Vienna Circle, a group of philosophers and scientists who sought to establish a scientific worldview, and is known for his work on the social origins of modern science. He explored the connections between science, technology, and society, and argued that scientific progress is driven by social and economic factors.
