Spencer Fayette Eddy (June 18, 1873 – October 7, 1939)[1] was an American diplomat who served as U.S. Minister to Argentina and Romania.

[4] At the time, "European diplomats consider Buenos Ayres the livest political centre in South America, particularly from the American point of view, and they regard Mr. Eddy's designation for the mission as a distinct and well-deserved compliment.

In August 1908, Eddy informed the Department of State, "of the vote by the Chamber of Deputies of a credit of $55,000,000 for additional armaments in view of the alleged hostile intentions of Brazil."

Nine days after he left his post in Argentina, he was appointed Minister to Romania and Serbia and Diplomatic Agent to Bulgaria on January 11, 1909.

[6] After fifteen years in the diplomatic service,[7] he resigned due to his wife's ill health and left his post on September 29, 1909.

[8] On April 26, 1906, Eddy was married to Lurline Elizabeth Spreckels (1886–1969) in Paris while he was an attaché at the American embassy in Saint Petersburg.
