Jacobi pronunciation

Carl Gustav Jacob Jacobi 10 December — 18 February was a German mathematician who made fundamental contributions to elliptic functions, dynamics , differential equations , determinants , and number theory. His name is occasionally written as Carolus Gustavus Iacobus Iacobi in his Latin books, and his first name is sometimes given as Karl.

Jacobi was born of Ashkenazi Jewish parentage in Potsdam on 10 December He was the second of four children of banker Simon Jacobi.

Jacobi name

His elder brother Moritz von Jacobi would also become known later as an engineer and physicist. He was initially home schooled by his uncle Lehman, who instructed him in the classical languages and elements of mathematics. In , the twelve-year-old Jacobi went to the Potsdam Gymnasium, where students were taught all the standard subjects: classical languages, history, philology, mathematics, sciences, etc.

As a result of the good education he had received from his uncle, as well as his own remarkable abilities, after less than half a year Jacobi was moved to the senior year despite his young age. However, as the University would not accept students younger than 16 years old, he had to remain in the senior class until He used this time to advance his knowledge, showing interest in all subjects, including Latin, Greek, philology, history and mathematics.

During this period he also made his first attempts at research, trying to solve the quintic equation by radicals. In Jacobi went to study at Berlin University , where he initially divided his attention between his passions for philology and mathematics.

Jacobi method

Jacobi did not follow a lot of mathematics classes at the time, finding the level of mathematics taught at Berlin University too elementary. He continued, instead, with his private study of the more advanced works of Euler , Lagrange and Laplace. By he understood that he needed to make a decision between his competing interests and chose to devote all his attention to mathematics.

In the same year he became qualified to teach secondary school and was offered a position at the Joachimsthal Gymnasium in Berlin.
