Gen. O.O. Howard, the white man from Maine for whom the leading African-American university was named, was W.T. Sherman's principal deputy in the march across the South and later headed the federal government's Reconstruction efforts. Though Reconstruction was fated to fail, Howard succeeded in fostering the creation of educational institutions for African-Americans. Not merely did he become an abolitionist, but he became a force for the equal treatment of racial minorities.
