Loomis was an amazing fellow, but spending time at Tuxedo Park didn't work out that well for Garret Hobart.
I did read Tuxedo Park. There is a Loomis Road in Bedford, MA near Hanscom AFB, site of the Air Force’s Electronic Systems Division. I noticed, that Ms. Conant, in passing, mentions that Raytheon made about half the “disks” used in World War II. Actually, Raytheon made about half the magnetrons used in World War II.
Percy Spencer saw the British multicavity magnetron which was machined out of a single block of copper. He realized that it could me made by bolting together sheets of stamped copper cut to right shape. The interior could be machined to achieve a smooth electrically continuous surface. His idea cut the cost of the magnetron dramatically. After the war, Spencer was credited with inventing the microwave oven.

The Invention that Changed the World, Robert Buderi. A lot of the same material, by a person with fewer personal contacts than the granddaughter of a former Harvard president, but better technical insight.
