John Stillwell is emeritus professor of mathematics at the University of San Francisco. His many books include Elements of Mathematics and Reverse Mathematics (both Princeton).
This book could well serve as a history of mathematics. ... [Stillwell] has done an amazing job of collecting and categorizing many of the most important ideas in this area. ---Jim Stein, New Books in Mathematics Stillwell's [The Story of Proof] joins his two other Princeton University Press books in having my highest recommendation. I just wish they had been around when I was a student. ---George Hacken, Computing Reviews
