How old is Grandma

That's pretty cool, but lots of that stuff was available to consumers before 1952. They may not have been perfected or mainstream, but available.
Television
Penicillin
Xerox
Air conditioners
Dishwashers
Clothes dryers
All were available before 1952.

And the ball point pen was sold in the U.S. around 1945.
