Who is Alexander Crummell from the book, W. E. B. Du Bois, 1868-1919: Biography of a Race?

Alexander Crummell, an Episcopal priest, spent twenty years as a missionary in Liberia. He went to speak at Wilberforce University in order to try and raise money for African Americans to move back and to help Liberians build schools for the many groups of native people living in the country. This man, along with Edward Wimont Blyden, was the first to think of the Pan African movement that Du Bois would later champion. At Wilberforce, Crummell gave a sermon called "The Destined Superiority of the Negro" which influenced Du Bois tremendously.
