W. E. B. Du Bois IQ

William Edward Burghardt Du Bois was born in Great Barrington, Massachusetts, in 1868. He studied at Fisk University, at Harvard and in Berlin, and in 1895 became the first African American to earn a PhD from Harvard. He wrote The Philadelphia Negro, a pioneering sociological study, and The Souls of Black Folk. He co-founded the NAACP in 1909 and edited its magazine, The Crisis, for 24 years. He moved to Ghana late in life and died there in 1963.

No figure exists. LifeScore lists about 155 as an editorial marker, range 140 to 170. It rests on his Harvard doctorate, studies in Berlin, pioneering data-based sociology and a large body of influential writing.

Du Bois's term, from The Souls of Black Folk (1903), for the experience of Black Americans of seeing themselves through the eyes of a society that looked on them with contempt, feeling "two-ness" as both American and Black.

He and his Atlanta University students created about 60 hand-drawn data visualisations of Black American life. Their bold, modern charts are now celebrated as pioneering information design.

Yes. From 1892 to 1894 he studied at the University of Berlin with leading economists and historians such as Gustav von Schmoller. He completed most of the work for a German doctorate but could not take the degree because of residency rules, and returned to finish his Harvard PhD.

Du Bois reasoned from data. He went door to door in Philadelphia to collect evidence and turned it into charts and arguments that challenged racist assumptions. Combining careful measurement with powerful writing is a rare analytical and verbal combination.

What supports it

• Harvard records his 1895 doctorate.
• His sociological studies and data visualisations survive.
• He wrote over 20 books.

What it cannot prove

• Severe barriers of race, slavery or disability shaped what records exist and what achievements were possible.
• Achievement reflects education, opportunity, persistence and collaboration as well as raw reasoning ability.
• An editorial marker is a comparison aid built from achievement, not a measurement, and two careful readers could place it ten points apart.

W. E. B. Du Bois's IQ is represented here by a retrospective estimate of 155, not a verified test result. W. E. B. Du Bois is best known for exceptional analytical research. The useful question is what the surviving evidence shows, not whether a precise modern score can be recovered.

Brilliant, proud and uncompromising. A scholar who became a fighter.

The dominant archetype here is The Scholar-Activist. This archetype shapes decision patterns: what feels natural, what creates friction, and what blind spots tend to emerge.

Estimated IQ is 155. This is a rough estimate based on documented accomplishments and contemporary accounts, not a literal measurement.

He died in Ghana on 27 August 1963, the day before the March on Washington.
