Julius wilhelm richard dedekind biography channel

Julius Wilhelm Richard Dedekind October 6, — February 12, was a German mathematician who did important work in abstract algebra particularly ring theory , algebraic number theory and the foundations of the real numbers. Dedekind was the youngest of four children of Julius Levin Ulrich Dedekind. As an adult, he never employed the names Julius Wilhelm.

He was born, lived most of his life, and died in Braunschweig often called "Brunswick" in English. In , he entered the Collegium Carolinum in Braunschweig, where his father was an administrator, obtaining a solid grounding in mathematics. Dedekind studied number theory under Moritz Stern. Gauss was still teaching, although mostly at an elementary level, and Dedekind became his last student.

This thesis did not reveal the talent evident on almost every page Dedekind later wrote. Thus Dedekind went to Berlin for two years of study, where he and Riemann were contemporaries; they were both awarded the habilitation in He studied for a while with Dirichlet, and they became close friends. Because of lingering weaknesses in his mathematical knowledge, he studied elliptic and abelian functions.

Around this time, he became one of the first to understand the fundamental importance of the notion of groups for algebra and arithmetic. East German stamp from , commemorating Richard Dedekind. When the Collegium Carolinum was upgraded to a Technische Hochschule Institute of Technology in , Dedekind returned to his native Braunschweig, where he spent the rest of his life, teaching at the Institute.

He retired in , but did occasional teaching and continued to publish.
