J.C. King
Joseph Caldwell 'J.C.' King was CIA chief of clandestine activities for the Western Hemisphere from 1947 through 1964, whose December 1959 memorandum recommending Castro's 'elimination' directly initiated Operation 40.
Joseph Caldwell "J.C." King (October 5, 1900, Brooklyn, New York - January 27, 1977, Washington, D.C.) served as chief of clandestine activities for the Western Hemisphere at the Central Intelligence Agency from 1947 through 1964, the longest-serving chief of that division during the Cold War's most active period of covert intervention in Latin America. Before the CIA, King served as vice president of Johnson & Johnson, overseeing its Brazil and Argentina subsidiary operations. His operational reach covered the 1954 CIA coup in Guatemala (PBSUCCESS), Bay of Pigs invasion planning, and the 1964 Brazilian coup, and his personal presence in Rio during the latter coup was recorded in Adolf Berle's diary. King is also the author of the first known written recommendation within the U.S. government that Fidel Castro be assassinated.
Early Life and Education
King was born October 5, 1900, in Brooklyn, New York, to Warren Charles King and Jessie Calhoun Caldwell. He attended the Lawrenceville School, graduating in June 1918, then briefly enrolled at Princeton University in September 1918 before transferring. He entered the United States Military Academy at West Point in November 1918 and graduated with the Class of 1923, Cullum Register No. 6992. After resigning his commission in May 1924, he attended the École Libre des Sciences Politiques in Paris, completing a diplomatic course in June 1925.1
Career at Johnson & Johnson
Following his studies in Paris, King built a business career in South America. He served as vice president of Johnson & Johnson, overseeing the company's subsidiary operations in Brazil and Argentina. Through that role he developed deep commercial and political networks across the hemisphere, cultivating contacts in government, industry, and military circles that he would later carry into intelligence work.
During World War II, King served as assistant military attaché in Argentina from July 1943 to November 1945, where he ran counterintelligence operations feeding deceptive information to Japanese agents. He was promoted to Major and awarded the Legion of Merit for this service, then promoted to Lieutenant Colonel in December 1945. He was released from military intelligence duty in 1946, later holding the rank of Colonel in the U.S. Army Reserve.2
He also served with the Office of the Coordinator of Inter-American Affairs (OCIAA) under Nelson Rockefeller from 1941 to 1945, stationed in Argentina, extending his wartime intelligence role beyond the military attaché function.3
Rise in the CIA's Western Hemisphere Division
King joined the Central Intelligence Agency in 1947 and eventually became chief of clandestine activities for the Western Hemisphere, a position he held through 1964. His CIA code name was Oliver G. Galbond. In that post he oversaw the full range of covert operations across Latin America, working within the CIA's Directorate of Plans.
An internal CIA historical staff document, "Western Hemisphere Division, 1946-1965," compiled in December 1973, covers the full arc of King's tenure at the division, from its formation through the mid-1960s.4
Guatemala and Operation PBSUCCESS
King's Western Hemisphere Division was central to the CIA's 1954 covert overthrow of Guatemalan President Jacobo Arbenz, code-named Operation PBSUCCESS. A declassified State Department document dated November 20, 1953 (FRUS 1952-54 Guatemala, Document 71) records King, then holding the title Chief of the Western Hemisphere Division within the CIA Directorate of Operations, attending a New York meeting to discuss reducing oil supplies to Guatemala as economic pressure against Arbenz. King met with an oil company executive to explore cutting fuel to the country, recording his assessment of the contact in writing.5
The December 1959 Cuba Memorandum and Operation 40
On December 11, 1959, Colonel King sent a confidential memorandum to CIA Director Allen Dulles that marked a turning point in U.S. policy toward Cuba. The memo argued that in Cuba there existed "a far-left dictatorship, which if allowed to remain will encourage similar actions against U.S. holdings in other Latin American countries." King recommended "thorough consideration be given to the elimination of Fidel Castro," the first known written recommendation within CIA channels for Castro's assassination, and stated that "violent action" was the only means to break Castro's grip on power, with the U.S. objective being "the overthrow of Castro within one year."6
Dulles forwarded the memorandum to the National Security Council within days. The NSC approved forming a working group to develop "alternative solutions to the Cuban problem," which became Operation 40. Dulles assigned Tracy Barnes as operating officer of what was also called the Cuban Task Force. The first Task Force meeting, chaired by Barnes, took place in his office on January 18, 1960, attended by David Atlee Phillips, E. Howard Hunt, Jack Esterline, and Frank Bender.7
King attended a White House meeting on March 17, 1960 where a plan entitled "A Program of Covert Action Against the Castro Regime" was presented to President Dwight Eisenhower, alongside CIA Director Dulles and Deputy Director for Plans Richard Bissell.8
The Raul Castro Assassination Plot
On July 21, 1960, King co-signed a TOP SECRET RYBAT OPERATIONAL IMMEDIATE cable with Tracy Barnes that authorized the first documented CIA assassination plot against Cuban revolutionary leadership. A Cuban pilot named Jose Raul Martinez had informed CIA officer William J. Murray that he had been selected to fly a chartered Cubana Airlines plane to Prague to pick up Raul Castro and other Cuban leaders. The King-Barnes cable instructed Murray to assess whether Martinez had "motivation sufficient to incur risk" in arranging a fatal accident during the return flight, and offered the pilot "$10,000, or a reasonable demand in excess of that" together with rescue facilities after the "accident." The cable stated that "possible removal of top three leaders is receiving serious consideration at HQS." A second cable, signed by Barnes alone, rescinded the plot after Martinez had already departed for Prague.9
CIA manager Jacob Esterline later stated that he protested the assassination plan directly to King, telling him: "J.C. do you realize that this is going to make people take this whole thing less seriously?"10
Bay of Pigs
At the first CIA Task Force meeting to plan the Bay of Pigs operation, held March 9, 1960, King stated that "unless Fidel and Raul Castro and Che Guevara could be eliminated in one package - which is highly unlikely - this operation can be a long, drawn-out affair and the present government will only be overthrown by the use of force." This assessment set the initial framing for the operation's dependency on decapitating Cuban leadership.11
On the evening of April 14, 1961, King traveled to New York with Tracy Barnes to brief exile leaders at the Cuban Revolutionary Council. He personally informed Dr. Miro Cardona "at dawn on the following day some action would take place." During the operation itself, King was effectively bypassed operationally by Bay of Pigs invasion manager Richard Bissell, a marginalization he resented. When General Maxwell Taylor convened the Green Study Group to investigate the failure, a memorandum for the record dated April 24, 1961 (FRUS 1961-63, Vol. X, Document 174) identified King's formal title as "Chief of the Western Hemisphere Division, Directorate for Plans," and noted that task force commander Esterline had directed complaints "to higher authority" - meaning King - who passed them upward without effect.12
After the Bay of Pigs, incoming CIA Director John McCone reorganized the Cuba account. Deputy Director of Plans Richard Helms took over the Cuba portfolio, and King's control over Cuban operations was formally removed. William Harvey took operational control of Cuban operations (Task Force W) from November 1961 through the Cuban Missile Crisis in fall 1962.13
British Guiana
The Western Hemisphere Division under King also oversaw CIA operations to destabilize Cheddi Jagan's government in British Guiana, culminating in its overthrow in 1964. A declassified account of those operations notes that "Western Hemisphere was under long-time chief Joseph C. King," with Virginia Hall Goillot as the branch chief directly handling British Guiana.14
Brazil and the 1964 Coup
Brazil was King's operational specialty, grounded in his years running Johnson & Johnson operations there. In the months before the April 1964 military coup against President Joao Goulart, King's Western Hemisphere Clandestine Services ran penetration operations against the Goulart government, including infiltrating the Peasant Leagues and financing urban anti-government demonstrations. CIA funding for anti-Goulart activities in 1962 alone was estimated at $5 to $20 million by different sources.15
A declassified March 28, 1964 Top Secret telegram from Ambassador Lincoln Gordon to Washington (FRUS 1964-68, Vol. XXXI, Document 187), classified IMMEDIATE EXDIS, lists King among the select recipients of sensitive intelligence on the unfolding military action - alongside Secretary of State Dean Rusk, Assistant Secretary Thomas Mann, Secretary of Defense Robert McNamara, General Maxwell Taylor, CIA Director John McCone, and CIA officer Desmond FitzGerald. The document's persons section identifies King as "Chief of the Western Hemisphere Division, Directorate of Plans, Central Intelligence Agency, until March 1964," fixing the end date of his operational tenure.16
King secretly flew to Brazil to be present when the coup occurred. Adolf Berle recorded in his diary: "Actually, King had been very quietly in Rio through the recent April revolution there. Some day we will get the story."17
King's Brazilian agent networks included penetration of the labor movement through the AIFLD, officers at the Higher War College, and the powerful Fourth Army.
Peru and Ecuador
King's Western Hemisphere Division was active in Peru and Ecuador during the early 1960s. In Peru, his operatives were unsympathetic to APRA leader Haya de la Torre's reform movement, and the local CIA station took no action to deter the July 1962 military coup. In Ecuador, King's counterpart in army intelligence was Major General Joseph A. McChristian, whose Green Beret team used JAARS aircraft for Amazon surveys.18
Retirement and Post-CIA Activities
King officially retired from the CIA in 1967 but returned as a CIA consultant. After leaving the agency, he became CEO of the Amazon Natural Drug Company, which operated as a CIA front organization. Based out of a houseboat, King supervised a network of Amazon indigenous people, anthropologists, and botanists to source toxic compounds from the region, including yage (the powerful hallucinogen used by the Yanomamo), for continued agency-related research.19
King died January 27, 1977, in Washington, D.C. He was buried with his third wife, Frances Anne Smith (married 1954), at the United States Military Academy Post Cemetery, West Point, New York. His previous marriages were to Cristina Patricia Pernas (1927) and Ana Vilma Gaspar (1942).20
