Tuxedo Park

I read this almost ten years ago, thinking it was about folks working on the Manhattan Project. I remember feeling a bit confused but didn't remember why. Today I understand why.

This book is 2/3rds biography of the author's family, an uncle's science fiction book that was based on top secret work he was involved in, and 1/3rd about the science his uncle, relatives, and their coworkers were creating. Sciences like radar, radiation, microwave, and cyclotrons to name a few.
