In the short story "Liar!", there is a mathematician named Peter Bogert.  In the short story "Frustration", there is a computer programmer named Peter Jonsbeck.

In the short story "Robbie" there is a character named George Weston.
In the short story "... That Thou Art Mindful of Him" there are robots named George Nine and George Ten.

I'd be surprised if there were not more examples.  Given how prolific Asimov was, and during a period without personal computers, I can't imagine that he kept track of such trivia as name reuse.
