Paul Stäckel

Paul Gustav Samuel Stäckel ( born August 20, 1862 in Berlin, † December 12, 1919 in Heidelberg ) was a German mathematician. He conducted research in the area of function theory, differential geometry, number theory (for example, Goldbach's Conjecture ) and history of non-Euclidean geometry. He also made ​​contributions in the field of mathematical education. In the field of prime numbers he used for the first time the concept of twin primes.

Life

Paul Stäckel was the son of School Board Ernst Gustav Stäckel († 1908) and his wife Marie Elisabeth Ringel. He was baptized Protestant. In 1886 he made ​​voluntary military service in Berlin, from 1914 to 1916 he served as a soldier in the First World War. In 1891 he married Eleanor Elizabeth Liidecke (* 1869, † after 1919). The marriage produced two sons and a daughter were born.

After graduation in 1880, he studied at the University of Berlin to study mathematics and physics, but also heard lectures on philosophy, psychology, education and history. A year later, he took the examination for teachers at secondary schools. His livelihood, he played first with teaching at secondary schools in Berlin. In 1885 he wrote his doctoral dissertation under Leopold Kronecker and Karl Weierstrass. Made in 1891, the Habilitation at the University of Halle. Later he worked as a professor at the University of Königsberg ( Associate Professor 1895-1897 ), the University of Kiel ( Associate Professor, 1897-1905 ), University of Hannover (1905 to 1908), the University of Karlsruhe ( 1908-1913 ) and the Ruprecht -Karls University of Heidelberg ( 1913-1919 ).

Stäckel employed, inter alia, to with the history of mathematics. He published the correspondence of Carl Friedrich Gauss with Wolfgang Bolyai, was involved in the publication of the works of Euler and Gauss ( for which he wrote a post Gauss as a geometer ) and gave the geometrical studies by Wolfgang and Johann Bolyai out (1913). He also translated works by Jakob Bernoulli, Johann Bernoulli, Augustin Louis Cauchy, Leonhard Euler, Joseph -Louis Lagrange, Adrien -Marie Legendre, Carl Gustav Jacobi into German for the series Ostwald classic.

In 1905 he was president of the German Mathematical Society.
