David Hilbert

Born in Königsberg in 1862, David Hilbert became one of the most influential mathematicians of the late 19th and early 20th centuries. He spent most of his career at the University of Göttingen, which became a world center for mathematical research during his time there.

Hilbert made major contributions across many areas, including algebra, number theory, geometry, analysis, and the foundations of mathematics. He is especially remembered for his work on the axioms of geometry and for presenting 23 problems in 1900 that helped set the agenda for much of 20th-century mathematics.

His ideas also reached into physics, especially through work connected with integral equations and the mathematical foundations that later influenced quantum theory. He died in Göttingen in 1943, leaving behind a legacy so broad that many concepts still carry his name, from Hilbert spaces to the Hilbert program.
