Teachers College in 1951 and obtained a master's degree in international law at American University in 1961 and a doctorate in philosophy from Catholic University in 1978.

Dr. Lambert also attended Georgetown University's School of Foreign Service, Catholic University's School of Fine Arts, Boston University's graduate school and summer programs at the Center for Moral Education at Harvard University.

Dr. Lambert was an elementary school teacher in the D.C. system from 1960 through 1967 and summer school principal from 1967 to 1969.

He then returned to D.C. Teachers College, where he served in many departments and became assistant to the dean in 1969. By 1974, he became assistant dean, a job he retained when the school was merged into the University of the District of Columbia in 1977.
