Jackie Robinson was 37 years old when he retired from Major League Baseball on Dec. 13, 1956. It was on that day when Robinson was traded from the Brooklyn Dodgers to the New York Giants for pitcher Dick Littlefield and $30,000. Robinson, however, opted to retire instead of accept the trade. On Jan. 14, 1957, Robinson submitted a formal retirement letter to Giants owner Horace Stoneham, and National League President Warren Giles approved the retirement two days later. In his letter, which he submitted on letterhead for Chock Full o' Nuts coffee, Robinson stated he was retiring to pursue other business interests. An announcement of Robinson's retirement appeared on Jan. 22, 1957, in Look Magazine.
