The Dulleses had served as United Fruit’s lawyers from their earliest days at Sullivan and Cromwell. On the eve of World War I, young Foster made a discreet tour of Central America on behalf of United Fruit, which was growing concerned about labor unrest and creeping Bolshevism in its tropical empire. Upon returning from his corporate spy mission, Foster made a confidential report to his uncle, Robert Lansing, who was not only a former counsel for United Fruit but President Woodrow Wilson’s secretary of state.
