As many as ten of the twenty-two Negro congressmen were men of college education. This training, however, varied widely in scope and purpose. Two men of this group became ministers of the gospel. One of them, Richard H. Cain[13] of South Carolina, was trained at Wilberforce University, Xenia, Ohio, whence he left in 1861, at the age of thirty-six years, to begin a career in his chosen field; the other, Hiram E. Revels[14] of Mississippi, was educated at the Quaker Seminary in Union County, Indiana. Prior to their election to Congress, both of these men attracted wide attention as churchmen. Cain was for four years the pastor of a church in Brooklyn, N. Y., after which his congregation sent him as a missionary to the freedmen of South Carolina. Senator Revels, on the other hand, was widely known as a lecturer in the States of Indiana, Illinois, Ohio, and Missouri. For some time he preached in Baltimore, taught school in St. Louis, and among other things, organized churches and lectured in Mississippi. The wide experiences of both gentlemen offered to them unusual opportunities to develop the power, keenness of insight, and knowledge of human nature so essential to the leadership of men. To some of these future Congressmen, the profession of teaching seemed more attractive than the ministry. Three of the number were destined to become educators. One of them, Henry P. Cheatham[15] of North Carolina, attended the public and private schools near the town of Henderson, and was later graduated with honor from the college department of Shaw University. Immediately thereafter, in 1882, he was elected to the principalship of the Plymouth State Normal School, where he served until 1895. The second member of this group, George W. Murray[16] of South Carolina, won by competitive examination a scholarship at the reconstructed University of South Carolina. There he remained until 1876, his junior year, when by the accession to power of an administration unfriendly to the coeducation of the races, he was forced to withdraw. For many years thereafter, Murray was engaged as a teacher in the schools of his native county. John Mercer Langston[17] of Virginia, the third member of the group of educators, was graduated, in 1849, at the age of twenty, from Oberlin College. Four years later, in 1853, he completed the work of the theological department of that school. Because of his ripe scholarship, moreover, unusual honors were conferred upon him by several American colleges and universities, and he was the recipient of several honorary memberships in scientific and literary institutions and associations of foreign countries. Indeed, there have sat in Congress few men of greater mental power and energy than John Mercer Langston.
