There’s a great story at The Undefeated: https://theundefeated.com/features/a-handshake-from-a-white-teammate-signaled-jackie-robinsons-arrival-in-americas-game/
Jackie Robinson’s first homer for the Montreal Royals came in their season opener on April 18, 1946. As he came across the plate, his white teammate, George Shuba, the next batter, smile, congratulated him, and shook his hand. It was a simple, natural gesture…and it was huge. Shuba later used a photo of the moment to teach his son to treat everyone equal.
Cap tip to George Shuba, being a decent human being is an excellent legacy.
