Karl Marx, Max Weber and Emile Durkheim are undoubtedly three of the most important theorists of all time. Their contributions to the world of sociology changed the minds of other theorists who followed them. One of these important theorists is known as WEB Du Bois, America's first sociologist of religion and a great social theorist of race. Du Bois was a truly inspiring individual who did many great things throughout his life. My goal is not only to explain who Du Bois was as a person, but to compare and contrast his theories with those of Marx, Weber, and Durkheim. Du Bois grew up in a relatively tolerant and integrated community in Barrington, Massachusetts. After graduating from Harvard, where he was the first African American to earn a doctorate, he became a professor of history, sociology and economics at Atlanta University. Du Bois was a co-founder of the National Association for the Advancement of Colored People (NAACP) in 1909. Racism was the primary focus of Du Bois's polemics, and he protested strongly against lynching, Jim Crow laws, and discrimination in education . and employment. His cause included people of color everywhere, especially Africans and Asians in their fight against colonialism and imperialism. Du Bois was also a prolific author. His collection of essays, The Souls of Black Folk, was a seminal work in African-American literature; and his 1935 magnum opus Black Reconstruction in America challenged the prevailing orthodoxy that blacks were responsible for the failures of the Reconstruction era. He wrote the first scientific treatise in the field of sociology; and has published three autobiographies, each of which contains in-depth essays on sociology, politics and history… in the middle of the paper… an approach focused on truly different aspects of the way he conducted his studies. Because he learned a lot from other theorists, he was able to take them and apply them in a completely new way, which allowed him to present his concepts differently. Du Bois now receives more attention than before, but is still not recognized by those like Marx, Weber or Durkheim. Du Bois' concepts will only become greater and more popular as time goes on, especially for his work on racism. In our world today many things are different regarding race and if Du Bois were here now I think he would be proud of where we have come. Although I feel we still have a long way to go. Overall, Du Bois made enormous contributions to sociology, and much of his work was learned from other great theorists of his time. All this contributed, in one way or another, to making the great sociologist he truly became.
