Hermann Schubert

Born in Potsdam in 1848, Hermann Schubert studied mathematics in Berlin and went on to build a career that joined teaching with original research. He became known for work on geometric counting problems—questions about how many lines, curves, or other figures meet certain requirements.

Schubert’s most influential book, Kalkül der abzählenden Geometrie (1879), helped organize and advance what is now called enumerative geometry. Later mathematicians gave a more rigorous foundation to many of his methods, but his ideas remained so fruitful that an entire area is still known as Schubert calculus.

He spent much of his professional life teaching in Hamburg while continuing his mathematical work, and he died in 1911. Today he is remembered as one of the key figures who helped turn classical geometric problems into a lasting part of modern mathematics.
