This is really strange. How are there two people with the same rare surname who make history, and have not just the same first name, but even the same middle letter? I'm curious if that family name is so rare that they are actually related, and whether it's some custom in that family to name the kids that way.
I spent a while trying to find a family connection but didn't succeed. There is an American custom for fathers to name their sons after themselves, as if trying to deny them their own identity; Bill Gates is the third William Henry Gates in a row, for example.
If it was not him, then it was another John B. Goodenough located not far from him in the mid-1970s (SofTech, Lowell, Massachusetts vs. MIT, Cambridge, Massachusetts)
