The Office of United States Director of Central Intelligence (DCI) was the head of the American Central Intelligence Agency from 1946 to 2005, acting as the principal intelligence advisor to the President of the United States and the United States National Security Council, as well as the coordinator of intelligence activities among and between the various U.S. intelligence agencies (collectively known as the Intelligence Community from 1981 onwards).
John Edward McLaughlin (born June 15, 1942) is the former Deputy Director of Central Intelligence and former Acting Director of Central Intelligence.
 His CIA career lasted more than 30 years starting in 1972 with a focus on European, Russian, and Eurasian issues in the Directorate of Intelligence.
 From 1984 to 1985, he served a rotational tour at the State Department in the Bureau of European and Canadian Affairs, where he was responsible for following European relations with the Middle East, Central America, and Africa.
 He served as Deputy Director and Director of the Office of European Analysis from 1985 to 1989; Director of Slavic and Eurasian Analysis from 1989 to 1995; Deputy Director for Intelligence, Vice Chairman for Estimates of the National Intelligence Council, and Acting Chairman of the National Intelligence Council from 1995 to 1997; and Deputy Director for Intelligence from 1997 to 2000 — heading up the Agency's analytical corps.
Roscoe Henry Hillenkoetter (May 8, 1897 – June 18, 1982) was the third director of the post-World War II United States Central Intelligence Group (CIG), the third Director of Central Intelligence (DCI), and the first director of the Central Intelligence Agency created by the National Security Act of 1947.
 He served as DCI and director of the CIG and the CIA from May 1, 1947 to October 7, 1950 and after his retirement from the United States Navy was a member of the board of governors of National Investigations Committee On Aerial Phenomena (NICAP) from 1957 to 1962.
William Oliver "Bill" Studeman (born January 16, 1940) is a retired Admiral of the United States Navy and former Deputy Director of the United States' Central Intelligence Agency, with two extended periods as Acting Director of Central Intelligence.
 As Deputy Director of Central Intelligence, he served in the administrations of George H. W. Bush and Bill Clinton under three Directors of Central Intelligence, Robert Gates, R. James Woolsey Jr., and John M. Deutch.
 Admiral Studeman retired from the Navy in 1995 after almost 35 years of service.
 Between 1988 and 1992 he was director of the National Security Agency; he was the Director of Naval Intelligence, from September 1985 to July 1988.
Robert James "Jim" Woolsey Jr. (born September 21, 1941) is a national security and energy specialist and former Director of Central Intelligence who headed the Central Intelligence Agency from February 5, 1993, until January 10, 1995.
 A lawyer by training and trade, he held a variety of government positions in the 1970s and 1980s, including as Under Secretary of the Navy from 1977 to 1979, and was involved in treaty negotiations with the Soviet Union for five years in the 1980s.
 His career also included time as a professional lawyer, venture capitalist and investor in the private sector.
William Joseph ("Wild Bill") Donovan (January 1, 1883 – February 8, 1959) was an American soldier, lawyer, intelligence officer and diplomat.
 Donovan is best remembered as the wartime head of the Office of Strategic Services (OSS), the precursor to the Central Intelligence Agency, during World War II.
 He is also known as the "Father of American Intelligence" and the "Father of Central Intelligence".
 "The Central Intelligence Agency regards Donovan as its founding father," according to journalist Evan Thomas in a 2011 "Vanity Fair" profile.
 The lobby of CIA headquarters, in Langley, Virginia, now features a statue of Donovan.
 Thomas observed that Donovan's "exploits are utterly improbable but by now well documented in declassified wartime records that portray a brave, noble, headlong, gleeful, sometimes outrageous pursuit of action and skulduggery."
The Intelligence Star is an award given by the Central Intelligence Agency to its officers for "voluntary acts of courage performed under hazardous conditions or for outstanding achievements or services rendered with distinction under conditions of grave risk".
 The award citation is from the Director of the Central Intelligence Agency and specifically cites actions of "extraordinary heroism".
 It is the third-highest award given by the Central Intelligence Agency, behind the Distinguished Intelligence Cross and Distinguished Intelligence Medal, and is analogous to the Silver Star, the US military award for extraordinary heroism in combat.
 Only a few dozen people have received this award (most posthumously), making it one of the rarest valor awards awarded by the US government.
A Director of Central Intelligence Directive (DCID) is a policy and guidance document issued by the Director of Central Intelligence that provides guidance and direction to members of the United States Intelligence Community.
 Many DCIDs have been superseded or modified by Intelligence Community Directives (ICD) issued by the Director of National Intelligence.
The National Intelligence Authority (NIA) was the United States Government authority responsible for monitoring the Central Intelligence Group (CIG), the successor intelligence agency of the Office of Strategic Services established by President Harry S. Truman's Executive Letter of 22 January 1946 in the aftermath of World War Two.
 The National Intelligence Authority and Central Intelligence Group were both replaced respectively by the National Security Council and the Central Intelligence Agency under the National Security Act of 1947 implemented on the 18 September 1947.
John Owen Brennan (born September 22, 1955) was the Director of the Central Intelligence Agency from March 2013 to January 2017.
 He has served as chief counterterrorism advisor to U.S. President Barack Obama; his title was Deputy National Security Advisor for Homeland Security and Counterterrorism, and Assistant to the President.
 His responsibilities included overseeing plans to protect the country from terrorism and respond to natural disasters, and he met with the President daily.
 Previously, he advised President Obama on foreign policy and intelligence issues during the 2008 presidential campaign and transition.
 Brennan withdrew his name from consideration for Director of the Central Intelligence Agency (CIA) in the first Obama administration over concerns about his support for transferring terror suspects to countries where they may be tortured while serving under President George W. Bush.
 Instead, Brennan was appointed Deputy National Security Advisor, a position which did not require Senate confirmation.
