David Hilbert

Definition

David Hilbert was a renowned German mathematician known for his foundational work in various fields such as algebra, geometry, and mathematical logic during the late 19th and early 20th centuries. He is particularly celebrated for Hilbert's program, which aimed to formalize all of mathematics using a complete and consistent set of axioms, significantly influencing the development of logical reasoning and proof skills in mathematics.
