Spruille Braden (March 13, 1894 – January 10, 1978) was an American diplomat, businessman, lobbyist, and member of the Council on Foreign Relations. He served as the ambassador of various Latin American countries, and as Assistant Secretary of State for Western Hemisphere Affairs. He is notable for his interventionist activities. His lobbying in ArgentinaagainstJuan Perón in 1946 ironically probably helped Perón win the presidency. More dramatically, Braden conceived what became the 1954 military coup in Guatemala.
Spruille Braden was the U.S. ambassador to Cuba in 1942. Author Ernest Hemingway had Braden's ear. In June 1942, Hemingway was able to secure Braden's support for Hemingway's scheme to patrol the Caribbean for GermanU-boats in his fishing boat, the Pilar. To this end, Braden provided Hemingway with necessary equipment, and eventually Hemingway did find and sink a U-boat.
