Bernard Bolzano


Welcome to the website Bolzano in Prague, which resulted from a meeting in 2017 celebrating two PhD theses on Bolzano’s mathematics. This was the third in a series of meetings which are linked from the Meetings page. As of December 2021, the website was rebuilt with the aim of offering broad support to anyone interested in Bolzano’s mathematics and related topics in logic and philosophy.

Bolzano is an unusual figure in the history of mathematics whose work spans the entire first half of the 19th century. By 1817 he had published original insights and contributions to fundamental properties of number, functions and geometric extensions, while later, among other things, he constructed the first fractal object and contributed to what became set theory. These achievements arose out of his original ideas on ‘well-grounded’ proofs.

Suggestions and material for inclusion on the website will be welcomed. All photos are property of the authors unless otherwise indicated.
