*P. G. L. Dirichlet; R. Dedekind*

A co-publication of the AMS and the London Mathematical Society

This volume is a translation of Dirichlet's

The book is suitable as a textbook, yet it also offers a
fascinating historical perspective that links Gauss with modern number
theory. The legendary story is told how Dirichlet kept a copy of
Gauss's

Also shown is how Gauss built on a long tradition in number
theory—going back to Diophantus—and how it set the agenda
for Dirichlet's work. This important book combines historical
perspective with transcendent mathematical insight. The material is
still fresh and presented in a very readable fashion.

This volume is one of an informal sequence of works within the
History of Mathematics series. Volumes in this subset,
“Sources”, are classical mathematical works that served as
cornerstones for modern mathematical thought. (For
another historical translation by Professor Stillwell, see

#### Readership

Graduate students and research mathematicians interested in number theory; mathematical historians.

#### Reviews & Endorsements

A new edition of Dirichlet's *Lectures on Number Theory* would be big
news any day, but it's particularly gratifying to see the book appear as
“the first of an informal sequence” which is to include “classical
mathematical works that served as cornerstones for modern mathematical
thought.” So all power to the American Mathematical Society and the London
Mathematical Society in their joint-venture History of Mathematics
series: may the “Sources” subseries live long and prosper. [T]his is quite
accessible, and could almost be used as a textbook still today. For those
who like to heed Abel's admonition to “read the masters, not their
students,” here's a great opportunity to learn more about Number Theory.
