Wesley Branch Rickey (December 20 1881 - December 9 1965) was an innovative Major League Baseball executive best known for two things: breaking baseball's color barrier by signing the African-American player Jackie Robinson, and later drafting the first Hispanic superstar, Roberto Clemente; and creating the framework to the modern minor league farm system. His many achievements, and somewhat theatrical religiosity, earned him the nickname "The Mahatma". Wikipedia
