There was an outfielder on that team named Hank Thompson. Bobby Thomson was white and Hank Thompson was black. I asked my father if they were brothers. He laughed and said: “No. You know how you can tell they’re not brothers?”
I said I didn’t. He said, “Hank Thompson spells his last name t-h-o-m-p-s-o-n. Bobby Thomson doesn’t have a ‘p’ in his last name. If they were brothers they would spell their names the same.”
It was years before I realized what a terrific thing that was to say to a kid.
