Investigations into isothermal surfaces formed the basis of the 1897 doctoral thesis submitted by Rudolf Ernst Rothe at the Humboldt University of Berlin. This academic beginning launched a career spanning several German institutions, during which he focused his mathematical research on differential geometry, function theory, and the practical application of these theoretical frameworks within the evolving field of engineering.
Academic Formation and Early Career
Born in Berlin on 15 October 1873, Rothe attended the Sophien-Gymnasium before commencing university studies in 1892. He learned under the guidance of mathematicians including Ferdinand Georg Frobenius, Lazarus Immanuel Fuchs, Johannes Knoblauch, and Hermann Amandus Schwarz. Following the completion of his doctorate, he pursued his habilitation at the Technische Hochschule Berlin-Charlottenburg in 1905. His teaching career included a professorship at the Clausthal University of Technology from 1908 to 1914, followed by a tenure at the Technische Hochschule Hanover, where he established the Institute for Applied Mathematics.

Returning to the Technische Hochschule Berlin in 1915, Rothe took on significant administrative and research duties. He served as rector of the institution in 1921. During World War I, his expertise was utilized for military research, specifically in the study of ballistics. He calculated trajectories for projectiles fired by the Paris gun, a weapon capable of striking targets from a distance of 120 kilometers. His later pedagogical work included authoring Higher mathematics for mathematicians, physicists and engineers, a six-part series first published in 1925.
Professional Appointments and Editorial Work
Rothe held leadership positions in several mathematical societies throughout his life. He served as the president of the Deutsche Mathematiker-Vereinigung in 1930 and acted as chair of the Berlin Mathematical Society during two separate terms: 1916–1918 and 1939–1941. Beyond his original research, he contributed to the preservation of mathematical history by completing the collected works of Karl Weierstrass after the death of Johannes Knoblauch. He also served as a co-editor with Felix Auerbach for the Taschenbuch für Mathematiker und Physiker, further editing the mathematical sections of the Hütte handbook during the 1930s.
Professional Recognition
In 1926, the German National Academy of Sciences Leopoldina elected Rothe as a member in recognition of his scholarly output. His career concluded with his retirement in 1939, at which point he was named an honorary senator of the Technische Universität Berlin. He remained a resident of Berlin until his death on 26 October 1942.
