Steinitz

Steinitz is a surname of German origin. It is associated with several notable figures in chess and mathematics, and with mathematical theorems named after them.

One of the most famous bearers is Wilhelm Steinitz, an Austrian-born chess player who became the first official World Chess Champion, holding the title from 1886 to 1894. He is regarded as a pioneer of modern chess theory and practice.

Ernst Steinitz was a German mathematician who helped lay the foundations of modern algebra and field theory. He contributed to the development of the theory of algebraic closures and the axiomatization of fields. Several theorems bear his name, including Steinitz's theorem in graph theory, which characterizes the graphs of convex polytopes as exactly the 3-connected planar graphs, and the Steinitz exchange lemma in linear algebra.

More broadly, the surname has appeared in academic contexts and is most commonly associated with these two figures, whose work has influenced chess theory and abstract algebra.
