Here are a few books on the history of recent mathematics that I recommend:

A History of Algebraic and Differential Topology, 1900 - 1960 by Jean Dieudonne.

by Catherine Goldstein, Norbert Schappacher, and Joachim Schwermer.

The Mathematical Coloring Book: Mathematics of Coloring and the Colorful Life of its Creators by Alexander Soifer.
