As a BIG Dodger fan, I am disappointed that I currently am not related to Branch Rickey (or to Jackie Robinson either)!
For those who don't know, Rickey was instrumental in forcing MLB to integrate (breaking the color barrier) through the signing of Jackie Robinson [Robinson-13] to a minor league contract and Jackie's subsequent promotion to the majors in 1947.
And the rest is history, so you can look it up yourselves!!
