Today it looks like he's beginning a series on radar, which is one of the unsung heroes of the war, overshadowed by other technological breakthroughs in codebreaking and the Manhattan Project. It was key to improved sub-hunting and developing over the horizon naval warfare and a good nightfighting ability for the Navy.
I hope he will tell the whole story of the Rad Lab and Alfred Loomis, but I don't know how much of that was declassified at this time.
You’d enjoy reading “Tuxedo Park : A Wall Street Tycoon and the Secret Palace of Science That Changed the Course of World War II” by Jennet Conant. Great book.
