When I was 8-10 years old, my brother watched on TV the animated series "Oh, these kids." And there Diddy Pickles (a red woman in glasses with a hairstyle in the shape of a chicken leg, Tommy's mother) often referred to the opinion of the famous child psychologist Livits.
I was an educated child. I knew for sure that Liffschitz was a physics scientist. And she could not understand why this strange American woman refers to a Russian physicist in matters of raising children.
