Fermat's Last Theorem: A Genetic Introduction to Algebraic Number Theory(Graduate Texts in Mathematics) <Vol. 50> (1st 1977. 3rd printing)

This book is an introduction to algebraic number theory via the famous problem of "Fermat's Last Theorem." The book also covers in detail the application of Kummer's ideal theory to quadratic integers and relates this theory to Gauss' theory of binary quadratic forms, an interesting and important connection that is not explored in any other book.
