I would be very upset about people never having heard of this great man except for one thing...
I’d never heard of him either until about 10 years ago when I saw a small article in some trivial section about fathers and sons. That sent me off on a quest to find out more about him.
Sadly, unless it has been written since then, there is not much about him.
Apparently he dared to openly disagree and say bad things about Saint FDR, so the liberal press has banished him. He was a FAR better man than FDR.
Remember TR’s other son Quentin died in WWI. Quentin Roosevelt was killed in aerial combat over France on Bastille Day (July 14), 1918.
Archie Roosevelt (another son) served WWI & WWII - won a Silver Star in New Guinea.
