Emil Artin and Helmut Hasse

From the book reviews: "There is extensive mathematical and biographical commentary accompanying the letters, making it possible to follow the discussion without having to be familiar with class field theory and its history. ... For anyone interested in the history of number theory in the 20th century, this book is a must-have." (Fernando Q. Gouvea, MAA Reviews, July, 2014)
