Eisenhower also integrated the armed forces. Truman issued the order to integrate the forces, but the brass largely ignored the order. Eisenhower knew how to browbeat generals and admirals, and actually got the job done.
And, interestingly, Wilson is responsible for resegregsting our armed forces after they had pretty much begun integrating on their own.
George Washington was said to have a fairly integrated army in his time too! He even had a few black officers. They were not very high up, but for his time, they did exist!
