This contract between Sigmund Freud and the Carnegie Endowment for International Peace, is signed by Freud and James S. Shotwell, the General Editor of the CEIP's seminal 150-volume series Economic and Social History of the World War. In December 1921, Freud, informing Shotwell that he "can't make any headway," asked to be released from the contract. In 1924, as the series was brought to a conclusion, Shotwell became director of the CEIP Division of Economics and History.
