David Rolfe Graeber is a London-based anthropologist and anarchist activist, perhaps best known for his 2011 volume Debt: The First 5000 Years. He is Professor of Anthropology at the London School of Economics.

His activism includes protests against the 3rd Summit of the Americas in Quebec City in 2001, and the 2002 World Economic Forum in New York City. Graeber was a leading figure in the Occupy Wall Street movement, and is sometimes credited with having coined the slogan, “We are the 99 percent”.
