Orleans seminaries responded in December 1950 by voting to establish the Seminary Extension Department. R. Lee Gallman, an Alabama pastor, was elected the first director of the program. Seminary Extension officially began operation in the Mississippi Baptist Building on June 15, 1951. Developing seminary type courses was Gallman's first task.
