Discovery of David Hilbert’s unpublished twenty-fourth problem originated from an examination of the mathematician’s personal manuscripts. This research, conducted by Rolf-Rüdiger Thiele, identified a mathematical challenge previously unknown to the academic community. By applying archival analysis to the history of science, Thiele has expanded the known record regarding figures such as Leonhard Euler and Felix Klein.
Academic Foundations and Early Career
Born in 1943 in Polepy, Bohemia, Thiele pursued higher education at the Martin Luther University of Halle-Wittenberg. He focused his studies on physics, mathematics, and psychology, ultimately receiving his doctoral promotion in 1973. Following his initial training, he gained experience in the publishing sector, working for firms including B. G. Teubner Verlag and Salomon Hirzel Verlag in Leipzig.

Thiele joined the Karl Sudhoff Institute for the History of Medicine and Natural Sciences at the University of Leipzig in 1986, where he remained until 2008. His career includes various visiting appointments, such as the chair for the history of natural sciences at Johannes Gutenberg University Mainz from 1992 to 1995. He also held academic roles at the University of Bonn and the University of Toronto.
Contributions to Mathematical History
In 2001, Thiele completed his habilitation at the University of Hamburg with a thesis concerning the history of the Bernoullian brachistochrone and the calibrator concept. He became a privatdozent at the University of Leipzig in 2002. His research frequently utilizes primary source material to examine analysis, the calculus of variations, and the biographies of mathematicians like Bartel Leendert van der Waerden.
Recognition and Recreational Mathematics
The Mathematical Association of America presented Thiele with the Paul R. Halmos – Lester R. Ford Award in 2004 for his publication regarding Hilbert’s twenty-fourth problem. Beyond his historical research, Thiele has authored several works on recreational mathematics and game strategy, frequently collaborating with Konrad Haase on titles involving puzzles and logical challenges.
