The sum of 4th, 6th, and 8th powers for the expression (1 + t^2)/(2 + t^2) provided a distinct challenge in the mid-1980s that only concluded when Bruce Reznick presented a solution in 1994. This problem originated from the research of German mathematician Eberhard Becker, a career academic whose professional life centered on the algebraic theory of quadratic forms and real algebraic geometry.
Academic Formation
Born in 1943 in Mecklenburg, Germany, Becker pursued his advanced studies at the University of Hamburg. He secured his doctorate in 1972, submitting a dissertation titled "Contributions to the theory of semi-simple quadratic algebra" under the supervision of Hel Braun. Four years later, in 1976, he finalized his habilitation at the University of Cologne, which prepared him for his subsequent faculty appointment in 1979 at the mathematics department of the University of Dortmund.

Becker spent his working life at the University of Dortmund, contributing significantly to the field of real algebraic geometry. His collaborative network included mathematicians such as Manfred Knebusch and Alex F. T. W. Rosenberg. Throughout his tenure, he prioritized the training of the next generation, supervising more than twelve doctoral students, including Markus Schweighofer, Susanne Pumplün, and Thorsten Wörmann. In recognition of his early academic contributions, he received the Kurt-Hartwig-Siemers-Wissenschaftspreis in 1970.
Institutional Leadership
Prior to his executive role, Becker held positions as institute director, dean, and member of the University of Dortmund Senate. On April 30, 2002, he assumed the office of rector following the resignation of Hans-Jürgen Klein. His administration is defined by the strategic rebranding of the institution to the Technical University of Dortmund. Despite opposition from various humanities departments, Becker secured the necessary two-thirds majority in the Senate to ratify the name change. He served in this capacity until September 1, 2008, when he was succeeded by Ursula Gather.
Retirement and Legacy
Becker formally retired on November 7, 2008, an occasion marked by a celebratory colloquium held by the faculty. His influence on the study of quadratic forms persisted long after his active teaching duties concluded. In October 2023, the university hosted a conference specifically focused on Quadratic Forms and Real Algebra to commemorate his 80th birthday.
