My father was born in 1910 so was an adult at the time of the Lindbergh kidnapping. My father always maintained that Lindbergh had the child killed because he felt the child was “defective”. I had rather thought my dad was wrong but now, knowing Lindbergh was a believer in eugenic maybe…
The Lindbergh child had a very large head. He was young so maybe just beginning to show signs of other defects.
Your father sounds like a true free thinker... and wise!
