After the 1960s, Forman spent the rest of his adult life organizing black people around issues of social and economic equality. He also taught at American University and other major institutions. He wrote several books documenting his experiences within the movement and his evolving political philosophy including ''Sammy Younge Jr.: The First Black College Student to Die in the Black Liberation Movement'' (1969), ''The Making of Black Revolutionaries'' (1972 and 1997) and ''Self Determination: An Examination of the Question and Its Application to the African American People'' (1984).
''The New York Times'' called him "a civil rights pioneer who brought a fiercely revolutionary vision and masterly organizational skills to virtually every major civil rights battleground in the 1960s."
