Kurt Hensel was a notable German mathematician born on December 2, 1861, in the city of Königsberg. He is best known for his contributions to the field of mathematical analysis and for his work on the theory of analytic functions. Hensel's research laid important groundwork for later developments in mathematics. One of Hensel's significant achievements is the introduction of the concept of p-adic numbers, which are a system of numbers used in number theory. His work has had a lasting impact on various areas of mathematics, influencing both theoretical research and practical applications in fields such as cryptography and algebraic geometry. Hensel passed away on April 1, 1941.
