Frank Parsons is considered the father of vocational guidance. In the 1890s, he organized the Boston Vocational Bureau to provide vocational assistance and trained teachers to be vocational counselors. In 1909, he published Choosing a Vocation, which discussed counseling techniques and divided counseling into personal investigation, industrial investigation, and organization and work. Others like Jessie B. Davis, Anna Y. Reed, Eli Weaver, David S. Hill, Carl R. Rogers, C. Gilbert Wrenn, and C. Harold McCully also contributed to the early counseling movement by establishing guidance services and advocating for vocational guidance and diversified curriculums.
