Key takeaways

  • John A. McCone belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect John A. McCone to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of John A. McCone from memory before moving on to harder problems.

Reference excerpt

John Alexander McCone (January 4, 1902 – February 14, 1991) was an American businessman and government official who served as Director of Central Intelligence from 1961 to 1965, during the height of the Cold War.

Background John A. McCone was born in San Francisco, California, on January 4, 1902. His father ran iron foundries across California, a business founded in Nevada in 1860 by McCone's grandfather. He graduated from the University of California, Berkeley in 1922 with a BS in Mechanical Engineering, beginning his career in Los Angeles' Llewellyn Iron Works. He rose swiftly and in 1929, when several works merged to become the Consolidated Steel Corporation, he became executive vice president. He also founded Bechtel-McCone. He also worked for ITT. In 1946, the General Accounting Office implied that McCone was a war profiteer, stating that McCone and his associates of the California Shipbuilding Corporation had made $44 million on an investment of $100,000. McCone's political affiliation was with the Republican Party. McCone served for more than twenty years as a governmental adviser and official, including positions on the Atomic Energy Commission in the Eisenhower Administration in 1958–1961 and with the Central Intelligence Agency (CIA) in the Kennedy Administration and the Johnson Administration in 1961–1965. His service in 1950–1951, as the second United States Under Secretary of the Air Force, was McCone's first taste of duty in the senior levels of the U.S. Government during the Truman Administration.

Atomic Energy Commission In 1958, he became chairman of the U.S. Atomic Energy Commission. According to journalist Seymour Hersh, in December 1960, while still Atomic Energy Commission chairman, McCone revealed CIA information about Israel's Dimona nuclear weapons plant to The New York Times. Hersh writes that President John F. Kennedy was "fixated" on the Israeli nuclear weapons program and one of the reasons that contributed to McCone's appointment as CIA director was his willingness to deal with this and other nuclear weapons issues – and despite the fact that McCone was a conservative Republican.

Director of Central Intelligence

After the disaster of the Bay of Pigs Invasion, President John F. Kennedy forced the resignation of CIA director Allen Dulles and some of his staff. McCone replaced Dulles as DCI on November 29, 1961. He married Theiline McGee Pigott on August 29, 1962, at St. Anne's Chapel of the Sacred Heart Villa in Seattle, Washington. McCone was not Kennedy's first choice; the President had tentatively offered the job to Clark Clifford, his personal lawyer, who politely refused (Clifford later served as Secretary of Defense for Lyndon Johnson); and then to Fowler Hamilton, a Wall Street lawyer with experience in government service during the Roosevelt and Truman administrations. Hamilton accepted, but when a problem developed at the Agency for International Development, he was shifted there. Thus Kennedy, urged on by his brother Robert, turned to McCone. As an agency "outsider" McCone lacked knowledge of how the CIA operated, as a result he relied heavily on his Deputy Director Dick Helms. He was not informed by the CIA of everything they were doing, despite being the Director of Central Intelligence. For instance, he was never told about mafia involvement in plots to assassinate Fidel Castro. He only found out about it in August 1962, when a Chicago Sun-Times reporter rang CIA headquarters asking if such plots had occurred. Nor was he told about the CIA's domestic surveillance program, HTLINGUAL. McCone was a key figure in the Executive Committee of the National Security Council (EXCOMM) during the October 1962 Cuban Missile Crisis. In the Honeymoon telegram of September 20, 1962, he insisted that the CIA remain imaginative when it came to Soviet weapons policy towards Cuba, as a September 19 National Intelligence Estimate had concluded it unlikely that nuclear missiles would be placed on the island. The telegram was so named because McCone sent it while on his honeymoon in Paris, France, accompanied not only by his bride, Theiline McGee Pigott but by a CIA cipher team. McCone's suspicions of the inaccuracy of this assessment proved to be correct, as it was later found out the Soviet Union had followed up its conventional military buildup with the installation of MRBMs (Medium Range Ballistic Missiles) and IRBMs (Intermediate Range Ballistic Missiles), sparking off the crisis in October when they were later spotted by CIA's Lockheed U-2 surveillance flights. After the assassination of John F. Kennedy, McCone received a call from the President's brother, Attorney General Robert F. Kennedy, asking McCone to come and see him. When he arrived, McCone was asked if the CIA had killed his brother. Kennedy later stated he asked this question "in a way that McCone couldn't lie to me, and they [the CIA] hadn't". McCone kept information from the Warren Commission, which had been set up to investigate President Kennedy's assassination. He never informed the commission about CIA assassination plots against Castro or the mafia's participation in these plots. While McCone was DCI, the CIA was involved in many covert plots; according to Admiral Stansfield Turner (who himself later served as DCI from 1977 to 1981, under President Jimmy Carter), these included:

In the Dominican Republic, the CIA had armed an assassination plot to take out President Rafael Leonidas Trujillo Molina. After the Bay of Pigs, Kennedy wanted the project stopped because it was too soon for another debacle. The problem is that once you encourage and arm a group of highly motivated locals, you can't just turn them off. Trujillo's enemies gunned him down dramatically, though technically speaking without U.S. help. In Laos, the CIA backed the Hmong (then known by the derogatory name Meo) people of the highlands to fight a counterinsurgency. This set off a complicated three-way civil war that hit the Hmong hard. In Ecuador, the CIA helped overthrow President José Velasco Ibarra. His replacement didn't last long before the CIA turned on him, looking for greater stability and allegiance. In British Guiana, the CIA stirred up trouble through the labor unions to take down the democratically elected Cheddi Jagan.

Worked examples

Example 1 — a first encounter with John A. McCone

Start with the simplest possible case. Write down what John A. McCone claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to John A. McCone before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about John A. McCone ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of John A. McCone

In research
John A. McCone appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses John A. McCone in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
John A. McCone is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1902 births, 1991 deaths, 20th-century American businesspeople, so understanding it makes those chapters shorter.
In everyday life
Look for John A. McCone outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
