Explanation:

William Edward Burghardt Du Bois was a prominent African-American human rights activist and academician of the first half of the 20th century. He is sometimes referred to as the 'father of Pan Africanism', and was active as a sociologist, historian, writer, editor, poet and teacher. He became a Ghanaian citizen at the age of 95, after the American government had denied him a new passport.

After graduating from Fisk University in 1888, Harvard turned out not to recognize his Fisk title. That is why he graduated cumlaude in 1890 with a new bachelor's degree at Harvard, where he also continued his studies. After obtaining his master's degree in history in 1892, he received a scholarship that allowed him to continue his education in Berlin. In Germany, where he stayed until 1894, he frequently collaborated with renowned sociologists, including Gustav von Schmoller. After his return, he obtained his PhD in 1895 as the first African-American in history at Harvard, on a thesis on the transatlantic slave trade.  

After teaching at Wilberforce University and later at the University of Pennsylvania, he was asked to set up the faculty of Sociology at the University of Atlanta (now Clark Atlanta University).
