David Rolfe Graeber (born 12 February 1961) is an American anthropologist and anarchist who is Reader in Social Anthropology at Goldsmiths, University of London. He was an associate professor of anthropology at Yale University, although Yale controversially declined to rehire him, and his term there ended in June 2007. Graeber has been involved in social and political activism, including the protests against the World Economic Forum in New York City in 2002 and Occupy Wall Street.

Economic history states that money replaced a bartering system, yet there isn't any evidence to support this axiom. Anthropologist Graeber presents a stunning reversal of this conventional wisdom. For more than 5000 years, humans have used elaborate credit systems to buy and sell goods. Since the beginning of the agrarian empires, humans have been divided into debtors and creditors. Through time, virtual credit money was replaced by gold and the system as a whole went into decline. This fascinating history is told for the first time.
