His paternal grandfather was a Swiss-born clockmaker naturalized as French.

He formed an important friendship with Herbrand, who had also been admitted at seventeen, one year before him. They took courses from the same excellent but dated mathematicians as Weil.
In — Herbrand did his military service and produced the work that Chevalley later said formed the basis of the new methods in class field theory.
An application of the Morse theory to the topology of Lie-groups
Herbrand spent — in Germany studying logic, and died on holiday in the Swiss Alps on the way back. Chevalley spent — studying number theory especially with Emil Artin at Hamburg and Chevalley theory of lie groups Hasse at Marburg and came back to earn his doctorate from the University of Paris in with a thesis on the work he did in Germany.
Class field theory had been at the top of the agenda in number theory since Teiji Takagi around proved a series of decades-old conjectures of Leopold Kronecker and David Hilbert. The proofs were extremely complicated, and the results were at once productive of concrete chevalley theory of lie groups theorems and promising of further theoretical advances.
The subject was prestigious and daunting. Carl Friedrich Gauss already used what are now called the Gaussian numbers Q[i] in arithmetic.

Yet the Gaussian integers do have unique prime factorization chevalley theory of lie groups to the ordinary integers. This is the prime factorization of 5 as a Gaussian chevalley theory of lie groups.
Using other algebraic irrationals in place of i gives other algebraic number fields K in place of the Gaussian numbers Q[i].
And each algebraic number field K contains a ring A of algebraic integers analogous to the Gaussian integers Z[i] although generally not so easy to describe. Class field theory began as an astonishing way to measure and work with failures of prime factorization. Each algebraic number field K extends to a certain larger field L K called the Hilbert class field, so that the Galois group of L K over K measures the failure of unique prime factorization in the ring A.
Furthermore, roughly speaking, all the algebraic integers in A have unique prime factorization in L K. A nontrivial Galois group for L K shows failure of prime factorization in A, and a larger Galois group shows greater failure.
Explicit descriptions of Hilbert class fields were known—some using classical complex analysis.
Other arithmetic properties of the ring A are expressed by the Galois groups of other extensions of K, which are also called class fields of various kinds.
The German number theorists would study any given algebraic number field K and its ring of algebraic integers A in connection with other related fields called local fields, so-called because these fields often concentrate attention on a single prime factor.
A less vivid term for infinite primes is Archimedean chevalley theory of lie groups. For each ordinary prime number p the p-adic numbers Qp focus on the chevalley theory of lie groups factor p. From this point of view the real numbers R focus on absolute valuewhich at first glance is nothing like a prime factor, but there are extensive axiomatic analogies.

The theory of prime factorization in any one local field is extremely simple because there is only one prime. The algebraic number fields K are global, as each one of these fields involves all the usual finite primes at once plus some infinite. Number theorists would calculate various class fields for K by quite complicated use of related local fields.
