1838–1919
A leading 19th-century German geometer, he helped shape projective and synthetic geometry through textbooks and research that influenced generations of mathematicians. He is especially remembered for work on line geometry and for the geometric figure now known as the Reye configuration.
Born in 1838 in Ritzebüttel, Germany, Theodor Reye studied mathematics and science in Göttingen and later taught at the Polytechnic School in Zurich before becoming a professor at the University of Strasbourg. He spent much of his career working in geometry, especially projective geometry, synthetic geometry, and line geometry.
Reye wrote influential mathematical texts, including Die Geometrie der Lage, which helped introduce modern geometric ideas to a wider audience in the German-speaking world. His name remains attached to the Reye configuration, a well-known object in geometry.
He died in 1919. Though not as widely known outside mathematics as some of his contemporaries, Reye played an important part in the development and teaching of 19th-century geometry.
