For 15 years Davis served in various education positions in Virginia, mostly with the public schools. He then went to work with the New York City-based General Education Board, where for the next 30 years he focused on rural and African American education in the southern United States and became an internationally known leader in his field.[5]
Virginia public schools
Upon graduating from the College of William and Mary in 1902, he first became the principal of the public schools of Williamsburg, Virginia, a small city where William and Mary is located. From 1903 to 1904, he was assistant secretary of the YMCA in the City of Roanoke. He was next principal of the Smyth County Public Schools in the incorporated town of Marion from 1904 to 1905.
In 1905, Jackson Davis was named Division Superintendent of Henrico County Public Schools, a school division in the large county which adjoins Richmond, where he served for five years. In 1908, he became professionally involved with another Virginian, Virginia Estelle Randolph, who was also to become well known in African-American education as they led Henrico County's role in beginning the work of the Jeanes Foundation.
Anna T. Jeanes was a wealthy Quaker who lived in Philadelphia. She had outlived her other family members. She has been described as "a remarkable woman with a vision for Christian peace which she used her fortune to promote."[6] As she neared the end of her life, she was approached by Dr. Booker T. Washington and others to see if she would help fund their efforts. If she could, she wanted to help "the little country schools", and set aside $1 million from her family inheritance to establish a fund called the Jeanes Foundation.[6] The purpose was to maintain and assist rural schools for African Americans in the South. The organization provided funds to employ supervisors of teachers who were dedicated to upgrading vocational training programs for teachers of black students.[7]
As the overseer of twenty three elementary schools in Henrico County, Virginia Randolph worked with Davis to develop the first in-service training program for black teachers and worked on improving the curriculum of the schools. With the freedom to design her own agenda, she shaped industrial work and community self-help programs to meet specific needs of schools.[8] She chronicled her progress by becoming the author of the Henrico Plan which became a reference book for southern schools receiving assistance from the Jeanes Foundation, which later became known as the Negro Rural School Fund.[9] The teachers were educated to use the procedures developed by Miss Randolph, Jackson Davis and others in normal schools such as at what is now Hampton University, Tuskegee University, and many other historically black colleges and universities (HBCUs).[10]
Dr. James H. Dillard, president of the Jeanes Foundation, credited Jackson Davis and Virginia Randolph as the inventors of the real Jeanes plan.[6] Their work together with the Jeanes Foundation development project helped both Davis and Randolph to commit the rest of their lives to rural and African American education.
In 1910, Jackson Davis was named State Agent for African-American rural schools for the Virginia State Department of Education. Serving from 1910 to 1915, during this time, he traveled extensively around Virginia, visiting communities, meeting teachers and pupils, and inspecting facilities. His surviving collection of photographs provided vivid graphical impact to accompany his reports from this period of the racially-segregated schools in Virginia.[11]
General Education Board
In 1915, Davis became affiliated with the General Education Board as a field agent. After two years, he was promoted to be the board's general field agent at headquarters in New York City. In 1929, he was named assistant director. He became associate director in 1933 and vice-president and director in 1946.[12]
For 30 years, Davis specialized in education and interracial problems in both the Southern United States, and in Africa, notably Belgian Congo and Liberia. In 1935 he went to Africa as a Carnegie visitor, and in 1944 went again as head of a group sent by the Foreign Missions Conference of North America, the British Conference of Missions, and the Phelps-Stokes Fund.[12]
Dr. Davis was also a trustee of the Phelps-Stokes Fund, an organization devoted to African-American education and race relations both in America and in Africa. He became vice-president of the fund in 1940, and succeeded Anson Phelps Stokes as president in 1946.[12]
In 1943, Dr. Davis was involved with the planning that led to creation of the United Negro College Fund (UNCF), stating "an effort of this kind would provide the form of expression which is needed to promote better interracial relations and that there are many people who would find this the most desirable way possible to express their good will toward the Negro."[13] Early supporters of the UNCF included President Franklin Delano Roosevelt and John D. Rockefeller Jr.[14]
He was also a frequent contributor to educational journals. In 1946, he co-authored Africa Advancing: A Study of Rural Education and Agriculture in West Africa and the Belgian Congo, with Margaret Wrong and Thomas M. Campbell. The book provided the results of an earlier survey (made in 1944).[12]
