The Brieskorn sphere remains a fundamental concept in differential topology, marking the primary contribution of the German mathematician Egbert Brieskorn. Born in Rostock in 1936, he dedicated his professional life to the intricate study of algebraic varieties and singularity theory, influencing generations of researchers through his rigorous analytical framework and extensive academic output before his death in 2013.
Academic Formation and Early Research
Brieskorn completed his formal education in mathematics and physics at Ludwig-Maximilians-Universität München and the University of Bonn. Under the supervision of Friedrich Hirzebruch, he earned his doctorate at Bonn in 1963 with a thesis focused on the differential-topological and analytical classification of specific algebraic manifolds. He subsequently achieved his habilitation in 1968, setting the stage for his tenure in higher education.

His career spanned several prominent institutions, beginning with his role as a Moore Instructor at the Massachusetts Institute of Technology in 1965. He later served as professor ordinarius at the University of Göttingen from 1969 to 1973. In 1973, he transitioned to the Sonderforschungsbereich Theoretische Mathematik in Bonn, and by 1975, he commenced his long-term professorship at the University of Bonn, which continued until his retirement in 2001.
Mathematical Legacy and Scholarly Contributions
Beyond his specialized research on Brieskorn-Grothendieck resolutions, he engaged deeply with the history of his discipline, notably acting as an editor for the collected works of Felix Hausdorff. His influence extended through his instruction of doctoral students, including Horst Knörrer, Peter Slodowy, Kyoji Saito, and Erhard Scholz. He was recognized for his academic service with the Cross of the Order of Merit of the Federal Republic of Germany.
