The Presidential Medal of Freedom is an award bestowed by the President of the United States and is—along with the comparable Congressional Gold Medal bestowed by an act of U.S. Congress—the highest civilian award in the United States. It recognizes those individuals who have made "an especially meritorious contribution to the security or national interests of the United States, world peace, cultural or other significant public or private endeavors". The award is not limited to U.S. citizens and, while it is a civilian award, it can also be awarded to military personnel and worn on the uniform.

It was established in 1963 and replaced the earlier Medal of Freedom that was established by President Harry S. Truman in 1945.

The Presidential Medal of Freedom is similar in name to the Medal of Freedom established by President Harry S. Truman in 1945 to honor civilian service during World War II, but much closer in meaning and precedence to the Medal for Merit: the Presidential Medal of Freedom is currently the supreme civilian decoration in precedence, whereas the Medal of Freedom was inferior in precedence to the Medal for Merit; the Medal of Freedom was awarded by any of three Cabinet secretaries, whereas the Medal for Merit was (and the PMOF is) awarded by the president. Another measure of the difference between these two similarly named but very distinct awards is their per-capita frequency of award: from 1946 to 1961 the average annual incidence of award of the Medal of Freedom was approximately 1 per every 86,500 adult U.S. citizens; from 1996 to 2011 the average annual incidence of award of the Presidential Medal of Freedom was approximately 1 per every 20,500,000 adult U.S. citizens (so on an annualized per capita basis, about 240 Medals of Freedom have been awarded per one Presidential Medal of Freedom).

The Medal of Freedom was a decoration established by President Harry S. Truman to honor civilians whose actions aided in the war efforts of the United States and its allies. It was intended to be awarded by the Secretary of State, the Secretary of War, or the Secretary of the Navy, but it is known that Presidents Dwight D. Eisenhower and John F. Kennedy also authorized awards.

Established on July 6, 1945, the Medal of Freedom may be awarded "to any person, not hereinafter specifically excluded, who, on or after December 7, 1941, has performed a meritorious act or service which has aided the United States in the prosecution of a war against an enemy or enemies and for which an award of another United States medal or decoration is considered inappropriate. The Medal of Freedom may also be awarded to any person, not hereinafter specifically excluded, who, on or after December 7, 1941, has similarly aided any nation engaged with the United States in the prosecution of a war against a common enemy or enemies. The Medal of Freedom shall not be awarded to a citizen of the United States for any act or service performed within the continental limits of the United States or to a member of the armed forces of the United States." The medal may be awarded posthumously.

Bob Dylan ( /ˈdɪlən/), born Robert Allen Zimmerman on May 24, 1941, is an American singer-songwriter, musician and artist. He has been an influential figure in popular music and culture for five decades. Much of his most celebrated work dates from the 1960s when he was an informal chronicler and a seemingly reluctant figurehead of social unrest. A number of Dylan's early songs, such as "Blowin' in the Wind" and "The Times They Are a-Changin'", became anthems for the US civil rights and anti-war movements. Leaving his initial base in the culture of folk music behind, Dylan's six-minute single "Like a Rolling Stone" has been described as radically altering the parameters of popular music in 1965. However, his recordings employing electric instruments attracted denunciation and criticism from others in the folk movement.

Dylan's lyrics incorporated a variety of political, social, philosophical, and literary influences. They defied existing pop music conventions and appealed hugely to the then burgeoning counterculture. Initially inspired by the songs of Woody Guthrie,Robert Johnson, and Hank Williams, as well as the music and performance styles of Buddy Holly and Little Richard, Dylan has both amplified and personalized musical genres. His recording career, spanning fifty years, has explored numerous distinct traditions in American song—from folk, blues and country to gospel, rock and roll, and rockabilly to English, Scottish, and Irish folk music, embracing even jazz and swing.

Stephen William Hawking, CH, CBE, FRS, FRSA (born 8 January 1942) is a British theoretical physicist, cosmologist, and author. His key scientific works to date have included providing, with Roger Penrose, theorems regarding gravitational singularities in the framework of general relativity, and the theoretical prediction that black holes should emit radiation, which is today known as Hawking radiation (or sometimes as Bekenstein–Hawking radiation).

He is an Honorary Fellow of the Royal Society of Arts, a lifetime member of the Pontifical Academy of Sciences, and in 2009 was awarded the Presidential Medal of Freedom, the highest civilian award in the United States. Hawking was the Lucasian Professor of Mathematics at the University of Cambridge between 1979 and 2009. Subsequently, he became research director at the university's Centre for Theoretical Cosmology.

Hawking has a motor neurone disease related to amyotrophic lateral sclerosis, a condition that has progressed over the years. He is now almost completely paralysed and communicates through a speech generating device. He has been married twice and has three children. Hawking has achieved success with works of popular science in which he discusses his own theories and cosmology in general; these include A Brief History of Time, which stayed on the British Sunday Times best-sellers list for a record-breaking 237 weeks.

William Herbert FoegeM.D., M.P.H. ( /ˈfeɪɡiː/; born 1936 in Decorah, Iowa) is an American epidemiologist who is credited with "devising the global strategy that led to the eradication of smallpox in the late 1970s".

Foege also "played a central role" in efforts that greatly increased immunization rates in developing countries in the 1980s.

His book, House on Fire: The Fight to Eradicate Smallpox (ISBN 978-0520268364) was published in June 2011.

Foege was born March 12^{[citation needed]} 1936 in Decorah, Iowa. He was the third of six children born to William A. Foege, a Lutheran minister, and Anne Erika Foege. The family lived in Eldorado, Fayette County, Iowa, starting in 1936 and moved to Chewelah, Washington, in 1945.

In his younger days he was inspired by the life of his uncle, a Lutheran missionary to New Guinea. He became interested in science at age 13 when working at a pharmacy, and read extensively about the world (e.g., Albert Schweitzer's work in Africa) while in a body cast for several months at age 15. When a teenager he expressed a desire to practice medicine in Africa.
