Adolf Berle

Adolf Augustus Berle Jr. (January 29, 1895 - February 17, 1971) was one of the most consequential and least-publicized architects of US Cold War Latin American policy. A Harvard Law-trained academic and corporate lawyer, Berle served as assistant secretary of state for Latin American affairs under President Franklin D. Roosevelt from 1938 to 1944, built the State Department's wartime intelligence coordination apparatus, served as US ambassador to Brazil from 1945 to 1946, and in retirement remained active in the Rockefeller network as a lawyer, political operator, and coup coordinator until his death in 1971. His Manhattan townhouse was the site from which he monitored the 1964 Brazilian coup by shortwave radio as it unfolded alongside coup conspirator Alberto Byington.¹

Berle was a founder of the New Deal brain trust and co-author (with Gardiner Means) of The Modern Corporation and Private Property (Macmillan, 1932), a foundational text of corporate liberalism that argued concentrated corporate power had superseded classical market competition. His political philosophy sought to preserve capitalism by reforming its excesses, a position that put him in perpetual tension with both the right (which he manipulated) and the left (which he despised). He distrusted communism as deeply as he distrusted fascism and built his career on the conviction that only American power could prevent either from dominating Latin America.²

Early Career and the Brain Trust

Berle entered Harvard College at age 14, earning his bachelor's degree in 1913 and master's degree in 1914, then graduated from Harvard Law School in 1916 at age 21, reportedly the second youngest graduate in the school's history after Louis Brandeis. He served as an intelligence officer in World War I and attended the Paris Peace Conference in 1919 as a junior delegate, resigning over the treaty's terms. He subsequently joined the law firm Berle, Berle and Brunner in New York City and was appointed professor of corporate law at Columbia University in 1927, a position he held until 1964.

From 1934 to 1938 he served as Chamberlain of New York City under Mayor Fiorello LaGuardia, while simultaneously advising Roosevelt's presidential campaign in 1932 and helping draft New Deal legislation as a member of the original "Brains Trust."³

The State Department and Intelligence Architecture

Berle joined the Roosevelt administration's State Department on March 7, 1938, appointed Assistant Secretary of State on March 5, and quickly established himself as the dominant figure on Latin American policy. By 1941 he had charge of intelligence coordination for the State Department, working with the FBI in Latin America and with the OSS in Europe.

He was the principal State Department advocate for the FBI Special Intelligence Service (SIS), which Franklin D. Roosevelt authorized on June 24, 1940 by presidential directive. The SIS extended FBI counterintelligence operations throughout Latin America as a counter to the German Abwehr and, by design, a counterweight to any future CIA encroachment on the Western Hemisphere. Under Berle's authority, SIS personnel were designated as "legal attaches" in nearly every US embassy in Latin America by the end of 1942, creating a network that placed over 340 undercover agents across the region.⁴

Berle and J. Edgar Hoover jointly backed Nelson Rockefeller's CIAA in its 1941 turf war with William J. Donovan's Coordinator of Information, ensuring that Donovan's future OSS was restricted to Europe and Asia.⁵ Berle's appointment as assistant secretary terminated December 19, 1944 when Rockefeller took the position, but Berle's institutional creations remained.

The Bureau of Intelligence and Research (INR), the State Department's permanent intelligence analysis organization, formally emerged in September 1945 when Harry S. Truman's Executive Order 9621 dissolved the OSS and transferred its Research and Analysis Branch to State. Berle's wartime coordination role was the institutional predecessor to this structure.⁶

Brazil Appointment and the 1945 Coup

When Rockefeller became assistant secretary of state in December 1944, he arranged for Berle to replace the existing US ambassador to Brazil, Jefferson Caffery. Berle was appointed January 18, 1945, presented his credentials to the Brazilian government on January 30, 1945, and took over the Rio de Janeiro embassy.

On September 28, 1945, Berle sent a lengthy telegram to Washington reporting on the political situation under Getulio Vargas and characterizing Vargas as endeavoring to keep things "on track" toward democratic elections. The following day he delivered a speech to the Associacao Brasileira de Imprensa in which he praised Brazil's promise of free elections. The opposition press immediately read the speech as a US warning to Vargas's queremista supporters, and Vargas later blamed Berle for encouraging the forces that moved against him.⁷

On October 29, 1945, General Pedro Goes Monteiro and the military high command forced Vargas to resign, ending his Estado Novo dictatorship. Berle's mission ended February 27, 1946. The episode is characterized in Brazilian historical scholarship as Latin America's first Cold War coup: the first postwar case in which the United States worked through diplomatic manipulation and military channels to remove a government pursuing economic nationalism rather than explicitly communist policies.⁸

The Kennedy Years

After his formal ambassadorship, Berle returned to Columbia and his law practice, but remained available for government service. In 1961, President John F. Kennedy named him Chairman of the Task Force on Latin America, an interdepartmental body that shaped US policy responses to Cuba and the broader hemispheric challenge. Berle attended the State Department planning meeting at which Kennedy asked William Fulbright to repeat his opposition to the Bay of Pigs invasion plan, with Berle and Thomas C. Mann in attendance and neither opposing the operation. He served as a consultant to the Secretary of State from 1961 to 1962.⁹

His oral history interview, conducted July 6, 1967 as part of the John F. Kennedy Presidential Library's oral history program, covers his views on Latin American relations, the Bay of Pigs, and the Alliance for Progress during the Kennedy administration.¹⁰

Advisory Role and the 1964 Coup

After his formal government service, Berle continued to operate as an adviser to Rockefeller and as a private intermediary with Brazilian political and military figures. He was a founding trustee of the Institute for International Labor Research, a Cold War anti-communist labor institution funded through AIFLD and other Rockefeller-network channels.¹¹

On the night of March 30-31, 1964, as the Brazilian military began its coup against President Joao Goulart, Berle was in his Manhattan townhouse monitoring the coup's progress by shortwave radio alongside Alberto Jackson Byington Jr. (1902-1964), a Sao Paulo businessman and Harvard graduate (class of 1924) who had been working to forestall a "Goulart dictatorship" and had, according to Berle's diary, "bought on his own credit a shipload of oil to make sure the Brazilian Navy would be able to function."¹²

Berle's diary entry of April 2, 1964, published in Navigating the Rapids, 1918-1971: From the Papers of Adolf A. Berle (Harcourt Brace Jovanovich, 1973, edited by Beatrice Bishop Berle and Travis Beal Jacobs), documents Byington's role in securing fuel for the navy and describes how Berle monitored the coup's unfolding. The published diary entry and its context appear on pages 788-789 of Navigating the Rapids and are cited in footnote 3 of FRUS 1964-68, Volume XXXI, Document 187, a March 28, 1964 telegram from Ambassador A. Lincoln Gordon to the Department of State and senior US officials.¹³

The FRUS Document 187 identifies Colonel J.C. King (Joseph Caldwell King, October 5, 1900 - January 27, 1977) as a recipient of Gordon's sensitive reporting. King was Chief of the Western Hemisphere Division of the CIA during the 1950s and 1960s. Before joining the CIA, King had served as vice-president at Johnson and Johnson in charge of Brazil and Argentina, and had then joined Nelson Rockefeller's Office of the Coordinator of Inter-American Affairs, establishing his Brazil connections in the same CIAA network where Berle had operated.¹⁴

The Berle-King-Rockefeller Triangle

A persistent operational triangle linked Berle (the diplomatic and political coordinator), J.C. King (the CIA's Western Hemisphere clandestine operations chief), and Nelson Rockefeller (the political principal). All three had been active in Brazil since the CIAA years. Their combined assets, diplomatic relationships, intelligence infrastructure, corporate holdings, and personal military contacts built over two decades, made the 1964 coup possible without requiring direct US military intervention. Alongside the covert network, the Johnson administration's military contingency planning (Operation Brother Sam, authorized March 31, 1964, with a naval task force, aerial convoy, and tanker fleet positioned to support the new government) provided the material backstop.¹⁵

His career demonstrates how informal personal networks, rather than formal institutional hierarchies, drove US Latin American policy, and how a single well-connected individual could move between government and private roles while maintaining operational continuity across administrations and decades.

Primary Sources

Berle kept detailed diaries throughout his career. The complete Adolf A. Berle Papers, 1912-1974, held at the Franklin D. Roosevelt Presidential Library in Hyde Park, New York, comprise 247 boxes arranged in 29 series and were donated between 1972 and 1982 by Mrs. Beatrice Berle. The collection covers his early career files, general and personal correspondence, State Department work, Brazil embassy files, and later advisory roles. The diaries for 1937-1971 form the core of the published volume Navigating the Rapids (Harcourt Brace Jovanovich, 1973).¹⁶

The State Department's biographical entry confirms his appointment and departure dates for both the assistant secretaryship and the Brazil ambassadorship.¹⁷

FRUS 1964-68, Volume XXXI (South and Central America; Mexico) contains the primary declassified diplomatic record of the period surrounding the 1964 coup, including Gordon's March 28, 1964 telegram (Document 187) with its footnote citation to Berle's diary; Dean Rusk's March 31, 1964 telegram authorizing contingency measures (Document 198); and related documents covering the period January through April 1964.¹⁸
