الترانزستور النقطي.
نصب تذكاري لنظرية جون باردين في المواد فائقة التوصيل في جامعة إلينوي.
ولد جون باردين في ماديسون بولاية ويسكونسن في 23 مايو 1908. وكان الابن الثاني للدكتور تشارلز راسل باردين وألثيا هارمر باردين. وكان واحدا من خمسة أطفال. وكان والده، تشارلز باردين، أستاذ علم التشريح وأول عميد لكلية الطب في جامعة ويسكونسن-ماديسون. ألثيا باردين، قبل الزواج، كانت تدرس في مدرسة مختبر ديوي، وبعد الزواج كانت شخصية مشهورة في عالم الفن.
ظهرت موهبة باردين في الرياضيات في وقت مبكر.وكان مدرس الرياضيات في الصف السابع يحثه ويشجعه علي متابعة مسائل متقدمة في الرياضيات, وحتي بعد سنوات عديدة كان باردين ما زال يدين لمدرسه بالفضل في حثه علي الاهتمام بالرياضيات.
حضر باردين المدرسة الثانوية الجامعية في ماديسون لعدة سنوات، ولكن تخرج من مدرسة ماديسون الثانوية الوسطى في 1923. وتخرج من المدرسة الثانوية في سن الخامسة عشر، على الرغم من انه كان من الممكن ان يتخرج قبل عدة سنوات. وكان تخرجه تأجل بسبب أخذ دورات إضافية في آخر المرحلة الثانوية، وأيضا بسبب وفاة والدته. دخل جامعة ويسكونسن ماديسون في عام 1923.واختار باردين الهندسة لأنه لم يرد أن يصبح أكاديميا مثل أبيه أستاذ علم التشريح وأيضا بسبب علاقة الهندسة الوثيقة بالرياضيات، كما شعر أن فرص الاشتغال بالهندسة ذات آفاق جيدة.
حصل باردين علي درجة البكالوريوس في الهندسة الكهربائية من جامعة ويسكونسن- ماديسون عام 1928.وقد تخرج في 1928 علي الرغم من تركه الجامعة لسنة ليعمل في شيكاجو.وكان قد اخذ جميع مقررات الفيزياء والرياضيات التي اثارت اهتمامه.كان بتردين قد اخذ سنة إضافية خلال دراسته في الجامعة مما اتاح له إكمال أطروحته في الماجستير والتي حصل عليها عام 1929 من جامعة ويسكونسن.كان باردين قد تأثر خلال دراسته بالكثير من علماء الرياضيات والفيزياء منهم بول ديراك(صاحب دالة ديراك-دلتا الشهيرة) وفرنر هايزنبرج(صاحب مبدأعدم التأكد في ميكانيكا الكم) وارنولد سومر.
فشل باردين في التقدم للحصول علي زمالة جامعتي ترينيتي وكامبريدج.
بقي باردين لبعض الوقت في ولاية ويسكونسن لإكمال دراساته، لكنه ذهب في نهاية المطاف للعمل في مختبرات الخليج للأبحاث، الفرع البحثي لشركة نفط الخليج، ومقرها في بيتسبرج. ،عمل باردين هناك على تطوير طرق لتفسير المسوحات المغناطيسية والجاذبية من 1930 حتي 1933، وقد عمل كجيوفيزيائي. ثم ترك العمل وقدم طلبا وتمت الموافقة على برنامج الدراسات العليا في الرياضيات في جامعة برنستون.
درس باردين كلا الرياضيات والفيزياء كطالب دراسات عليا، وانتهى بكتابة اطروحته حول مشكلة في الفيزياء الحالة الصلبة، تحت إشراف الحائز على جائزة نوبل الفيزياء يوجين ويغنر. قبل إكمال رسالته، عرض عليه منصب زميل جديد لجمعية الزملاء في جامعة هارفارد في عام 1935. وأمضى السنوات الثلاث التالية هناك ،من 1935 حتى 1938 ،عمل هناك مع الحائز علي جائزة نوبل هاسبروك فيلك وبيرسي بريدجمان –الذي حاز على جائزة نوبل فيما بعد- في دراسة التوصيل الكهربي في المعادن. حصل باردين على شهادة الدكتوراه في الفيزياء الرياضية من جامعة برينستون في 1936.

John Bardeen (May 23, 1908 – January 30, 1991) was an American physicist and electrical engineer, the only person to have won the Nobel Prize in Physics twice: first in 1956 with William Shockley and Walter Brattain for the invention of the transistor; and again in 1972 with Leon N Cooper and John Robert Schrieffer for a fundamental theory of conventional superconductivity known as the BCS theory.
The transistor revolutionized the electronics industry, allowing the Information Age to occur, and made possible the development of almost every modern electronic device, from telephones to computers to missiles. Bardeen's developments in superconductivity, which won him his second Nobel, are used in Nuclear Magnetic Resonance Spectroscopy (NMR) or its medical sub-tool magnetic resonance imaging (MRI).
In 1990, John Bardeen appeared on LIFE Magazine's list of "100 Most Influentia

John Bardeen was born in Madison, Wisconsin on May 23, 1908.[2]
Bardeen attended the University High School at Madison for several years, but graduated from Madison Central High School in 1923.[2] He graduated from high school at age fifteen, even though he could have graduated several years earlier. His graduation was postponed due to taking additional courses at another high school and also partly because of his mother's death. He entered the University of Wisconsin–Madison in 1923. While in college he joined the Zeta Psi fraternity. He raised the needed membership fees partly by playing billiards. He was initiated as a member of Tau Beta Pi engineering honor society. He chose engineering because he didn't want to be an academic like his father and also because it is mathematical. He also felt that engineering had good job prospects.[3]
Bardeen received his B.S. in electrical engineering in 1928 from the University of Wisconsin–Madison.[4] He graduated in 1928 despite taking a year off during his degree to work in Chicago.[5] He had taken all the graduate courses in physics and mathematics that had interested him, and, in fact, graduated in five years, one more than usual; this allowed him time to also complete a Master's thesis, supervised by Leo J. Peters. He received his M.S. in electrical engineering in 1929 from Wisconsin.[4]
Bardeen stayed on for some time at Wisconsin furthering his studies, but he eventually went to work for Gulf Research Laboratories, the research arm of the Gulf Oil Corporation, based in Pittsburgh.[1] From 1930 to 1933, Bardeen worked there on the development of methods for the interpretation of magnetic and gravitational surveys.[2] He worked as a geophysicist. After the work failed to keep his interest, he applied and was accepted to the graduate program in mathematics at Princeton University.[3]

American physicist William Shockley led the team of scientists that developed the first amplifying semiconductor, the transistor, on 23 December 1947. He shared the 1956 Nobel Prize for Physics with John Bardeen and Walter H. Brattain, two of his colleagues at Bell Laboratories in Murray Hill, New Jersey. Though the device was largely conceived by Shockley, he was only peripherally involved in developing it, but as supervisor he was credited as co-inventor. Exactly one month after their accomplishment, however, Shockley alone developed the junction transistor, a three-layer sandwich-style miniature mechanism in which a small electrical charge signal on the inner layer modulates the current as it flows through. It was another important breakthrough in the developing electronics era, but after their transistor project Bardeen and Brattain, rankled at what they perceived as his hogging of the credit, both refused to work with him again.

On his father's side he was proud to be directly descended from the Mayflower pioneers, and he was home educated until he was about ten years of age, factors which perhaps contributed to his difficulty getting along with supervisors and co-workers. Doubtless, though, much of Shockley's frustration with others came from years of being the smartest person in the room, in whatever room he entered. As a boy he was one of the "gifted" children studied by Lewis Terman in his pioneering but racially-tainted work with intelligence tests.

As an adult he attended Cal Tech and MIT, and in 1939 he designed one of the first nuclear reactors. His findings, however, were immediately classified as national security secrets, leaving Shockley unable to publish his paper. His work on nuclear reactions, filed away but not fully understood by federal bureaucrats, remained classified during World War II, even as the Manhattan Project's scientists followed similar lines of inquiry without access to his work. Shockley, meanwhile, worked on the US Navy's Anti-Submarine Warfare Operations Group during the war, and his calculations led to improved accuracy in Allied submarines' attacks on German U-boats. He was also involved in training pilots for the Army Air Corps, and devised a strategy that helped defend trans-Atlantic supply convoys from Axis air attack.

In 1955, with funding from Arnold Beckman, he founded Shockley Semiconductor in Palo Alto, California. The company is heralded as the first Silicon Valley business, but it was never profitable and within a few years it was absorbed into Beckman Industries and sold. Shockley had hired the brightest minds in transistor science, but in 1957, frustrated by his dictatorial tactics and increasing paranoia, eight of his best researchers (still called the "traitorous eight") quit to start their own company, Fairchild Semiconductor. At Fairchild, they had immediate success while Shockley's endeavor faltered, and he turned to teaching at nearby Stanford University.

At Stanford he became intrigued by racial questions and population control, and began publicly claiming that blacks are less intelligent than whites, by genetics and heredity. When his comments were criticized as racist, Shockley doubled down and reveled in the controversy, stating that humanity's future was threatened because people with low IQs were having more children than people with high IQs. He was basically espousing eugenics, an idea that had been routinely accepted by scientists in the early 20th century but was well debunked by Shockley's time. He sought expert status in genetics, a science far outside his training and experience, and soon became a pariah in the scientific community. In a 1980 interview, when asked if his views amounted to racism, he famously answered "If you found a breed of dog that was unreliable and temperamental, why shouldn't you regard it in a less favorable light?" In 1982 he ran for the US Senate on a platform calling for sterilization of people with IQs lower than 100. In his latter years, at any event where Shockley spoke he was greeted by picketers.

His first marriage ended in divorce, with Shockley leaving his wife as she battled uterine cancer. Months later he married his second wife, a psychiatric nurse, who became virtually his only friend in his later years. He was estranged from all three of his children, and died of prostate cancer in 1989. There was no funeral service, because his wife was certain that no-one but she would have come. His name remains controversial even in death — his wife died in 2007, leaving 28 acres of land for a park in Auburn, California, with the stipulation that it be named The Nobel Laureate William B. Shockley and his wife Emmy Shockley Memorial Park. Minority and civil rights groups have objected, and the city has not yet decided whether to accept the gift.
