Teaching
Tolbert's distinguished teaching career began at Loma Linda University in 1968 where he taught the first course in African American History there. He also taught courses on American history and the American constitution. While working on his doctorate at UCLA, Tolbert was an instructor at California State University, San Bernardino, University of Southern California, UCLA and UCSD, all in his middle to late 20s.
From 1973 to 1981 Tolbert was an assistant professor in the department of History at University of California at San Diego. At UCSD he taught the first courses in African American History and initiated an MA program in Social and Ethnic History. From 1984-1991 he was an associate and full professor at California State University at Fullerton in the department of History and the department of Afro-American and Ethnic Studies. In 1987 he became Chairman of the Afro-American and Ethnic Studies Department.
Howard University
In 1991, Tolbert assumed the position of chair of Howard University's History department. He would hold this post until 1998, then serve as chair again from 2002 to 2005, and 2009.[3]
While at Howard Tolbert helped to incorporate a geography program; expand the public history program; initiate the historical research for the New York Burial Ground Project;[4] directed twenty PhD dissertations; and served as chairman of over three dozen dissertation committees.
Contribution
Tolbert's specialty is Garveyism. His 1980 The UNIA and Black Los Angeles, was the first regional study of the Marcus Garvey movement.[5] He has written and edited numerous books on the subject; served on scores of committees and panels; given hundreds of presentations;[6] and enhanced the scholarship greatly on the subject. He has especially shed light on the effect of Garveyism in Los Angeles, the Los Angeles metropolitan area and California,[7] conducting studies on various UNIA chapters nationwide.
Recently Tolbert has been active in the Sabbath in Africa movement (SIA), sitting on its board and giving presentations across the world.[8] The SIA generates scholarship on Christianity in Africa, operating on the premise that Christianity is a native African religion and has survived there uninterrupted since its inception during Pentecost.[9]
Additionally, Tolbert is known to have one of the largest personal collections of African-American memorabilia.[10]
