Mr. William Tecumseh Sherman Jackson succeeded Mrs. Cooper in 1906. He was educated at Amherst College which conferred upon him the degrees of A.B. in 1892 and A.M. in 1897. He thereafter pursued postgraduate studies at the Catholic University of America. Mr. Jackson's twenty-five years of service have all been in the high school. He was teacher of mathematics from 1892 to 1904, principal of M Street High School from 1906 to 1909 and has been head teacher in the Department of Business Practice from 1912 to the present time. In commenting upon Mr. Jackson's work, one of his superior officers declared that he "introduced the individual promotion system, stimulated interest in athletics and fostered the school spirit." Mr. Edward Christopher Williams succeeded Mr. Jackson as principal of the M Street High School in 1909. He was graduated from the Central High School in Cleveland, Ohio, holds the degree of B.L. from the Western Reserve University, and an honor certificate from the New York State Library School. He was Librarian of the Western Reserve University from 1894 to 1909, and was instructor in bibliographical subjects in the Western Reserve University Library School from 1904 to 1909. After serving seven years as principal of the M Street High School, he resigned June, 1916, to accept a position in Howard University as Librarian and Director of the Library School. Mr. Williams achieved success as an administrative officer while principal of the M Street High School. Mr. G. C. Wilkinson, the present principal of this school, was educated in the public schools of the District of Columbia, finishing the course at the M Street High School in June, 1898. He was graduated from Oberlin, with the degree of A.B. in 1902, and from the Law Department of Howard University in 1909. In 1902 he was appointed teacher in the M Street High School and discharged his duties in the new field of action with enthusiasm and zeal. During these years Mr. Wilkinson devoted much of his time after school hours to the training and instructing of athletic teams, particularly football and baseball, at a time when physical training for high school boys was not an established part of the regular curriculum. This interest was not confined to M Street High School only but extended to all secondary schools of the vicinity and resulted in the formation of the Inter-Scholastic Athletic Association of the Middle Atlantic States under whose auspices track meets and basket ball were first introduced into the capital of the nation. Thus athletic interest was extended, until they were registered in the Amateur Athletic Union of America as the first and at present the only football officials of color in America. Mr. Wilkinson was equally active in assisting the military organization of the high school. In November, 1912, Mr. Wilkinson was promoted to the principalship of the Armstrong Manual Training School and transferred to the principalship of the Dunbar High School, July
