Children's ✦ Penny’s Take
Geometry's Great Thinkers
Bonnie Leech · 2006
72/100
👍 Worth It
For a school-library supplementary book, this does its job unusually well: it grounds abstract geometry in real human stories and makes a point of including Grace Chisholm Young alongside the usual Pythagoras-and-Euclid lineup. The coverage is necessarily shallow at this length, and a 2005 publication date means some supporting material will feel dated, but the core historical content holds up fine for classroom use.
