Editing John Bardeen (section)

==Personal life==
Bardeen married Jane Maxwell on July 18, 1938. While at Princeton, he met Jane during a visit to his old friends in [[Pittsburgh]].

Bardeen was a scientist with a very unassuming personality. While he served as a professor for almost 40&nbsp;years at the University of Illinois, he was best remembered by neighbors for hosting cookouts where he would prepare food for his friends, many of whom were unaware of his accomplishments at the university. He would always ask his guests if they liked the hamburger bun toasted (since he liked his that way).  He enjoyed playing [[golf]] and going on [[picnic]]s with his family.  [[Lillian Hoddeson]] said that because he "differed radically from the popular stereotype of 'genius' and was uninterested in appearing other than ordinary, the public and the media often overlooked him."<ref name="knightridder"/>

When Bardeen was asked about his beliefs during a 1988 interview, he responded: "I am not a religious person, and so do not think about it very much". However, he has also said: "I feel that science cannot provide an answer to the ultimate questions about the meaning and purpose of life." Bardeen did believe in a code of moral values and behavior.<ref>{{cite book|title=True Genius: The Life and Science of John Bardeen|url=https://archive.org/details/truegeniuslifesc0000hodd|url-access=registration|year=2002|publisher=Joseph Henry Press|isbn=9780309169547|first1=Lillian|last1= Hoddeson|first2=Vicki|last2= Daitch|quote=John's mother, Althea, had been reared in the Quaker tradition, and his stepmother, Ruth, was Catholic, but John was resolutely secular throughout his life. He was once "taken by surprise" when an interviewer asked him a question about religion. "I am not a religious person," he said, "and so do not think about it very much." He went on in a rare elaboration of his personal beliefs. "I feel that science cannot provide an answer to the ultimate questions about the meaning and purpose of life. With religion, one can get answers on faith. Most scientists leave them open and perhaps unanswerable, but do abide by a code of moral values. For a civilized society to succeed, there must be a common consensus on moral values and moral behaviour, with due regard to the welfare of our fellow man. There are likely many sets of moral values compatible with successful civilized society. It is when they conflict that difficulties arise."}}</ref> John Bardeen's children were taken to church by his wife, who taught Sunday school and was a church elder.<ref name="trueGenius">Daitch & Hoddeson (2002).

She and John agreed that the family could, if they wanted to, have a memorial service conducted by friends and family, "but not a sermon by a stranger, who, if a minister, is bound to dwell on life after death and other religious ideas in which we have no faith."}}</ref> He was the father of [[James M. Bardeen]], [[William A. Bardeen]], and daughter Elizabeth.

{{quote box|align=right|width=33%|quote = Near the end of this decade, when they begin enumerating the names of the people who had the greatest impact on the 20th century, the name of John Bardeen, who died last week, has to be near, or perhaps even arguably at, the top of the list ... Mr. Bardeen shared two Nobel Prizes and has been awarded numerous other honors.  But what greater honor can there be when each of us can look all around us and everywhere see the reminders of a man whose genius has made our lives longer, healthier and better.|source= —''[[Chicago Tribune]]'' editorial, February 3, 1991}}

In honor of Bardeen, the engineering [[Quadrangle (architecture)|quadrangle]] at the University of Illinois at Urbana-Champaign is named the [[Engineering Campus (University of Illinois Urbana-Champaign)|Bardeen Quad]].

Also in honor of Bardeen, [[Sony]] Corporation endowed a $3&nbsp;million John Bardeen professorial chair at the University of Illinois at Urbana-Champaign, beginning in 1990.<ref name=obit>{{cite news|author=John Noble Wilford |url=https://www.nytimes.com/1991/01/31/obituaries/dr-john-bardeen-82-winner-of-nobel-prize-for-transistor-dies.html |quote=John Bardeen, a co-inventor of the transistor that led to modern electronics and twice a winner of the Nobel Prize in Physics, died yesterday at Brigham and Women's Hospital in Boston.

At the time of Bardeen's death, then-University of Illinois chancellor Morton Weir said, "It is a rare person whose work changes the life of every American; John's did."<ref name="chisuntimes2"/>

Bardeen was honored on a March 6, 2008, United States [[postage stamp]] as part of the "American Scientists" series designed by artist [[Victor Stabin]]. The $0.41 stamp was unveiled in a ceremony at the University of Illinois.<ref>{{cite web |url=http://www.engr.uiuc.edu/news/?xId=072808960714 |title=Bardeen Stamp Celebrated at Campus Ceremony |access-date=March 4, 2008 |publisher=University of Illinois }}</ref>  His citation reads: "Theoretical physicist John Bardeen (1908–1991) shared the Nobel Prize in Physics twice—in 1956, as co-inventor of the transistor and in 1972, for the explanation of superconductivity.  The transistor paved the way for all modern electronics, from computers to microchips.  Diverse applications of superconductivity include infrared sensors and medical imaging systems."  The other scientists on the "American Scientists" sheet include biochemist [[Gerty Cori]], chemist [[Linus Pauling]] and astronomer [[Edwin Hubble]].
