It opened on Broadway at the Royale Theatre on 11 April 2000 and ran for 326 performances. Directed by Michael Blakemore, it starred Philip Bosco (Niels Bohr), Michael Cumpsty (Werner Heisenberg), and Blair Brown (Margrethe Bohr). It won the Tony Award for Best Play, Best Featured Actress in a Play, Blair Brown, and Best Direction of a Play (Michael Blakemore).
Three spirits come together to try to apprehend and explain one simple question: "Why did Heisenberg go to Copenhagen?" The rest of the play details information around this subject through argument and interjections.[1]
Heisenberg – "No one understands my trip to Copenhagen. Time and time again I've explained it. To Bohr himself, and Margrethe. To interrogators and intelligence officers, to journalists and historians. The more I've explained, the deeper the uncertainty has become. Well, I shall be happy to make one more attempt."
Along the way, Heisenberg and Bohr "draft" several versions of their 1941 exchange, arguing about the ramifications of each potential version of their meeting and the motives behind it. They discuss the idea of nuclear power and its control, the rationale behind building or not building an atomic bomb, the uncertainty of the past and the inevitability of the future as embodiments of themselves acting as particles drifting through the atom that is Copenhagen.
Characters
In most dramas in which the characters are based on real people, there is a point at which the character deviates from the real person. However, playwright Michael Frayn worked to keep that distinction as small as possible. Having studied memoirs and letters and other historical records of the two physicists, Frayn felt confident in claiming that "The actual words spoken by [the] characters are entirely their own." With that in mind, the character descriptions apply to both the representative characters as well as the physicists themselves. There is a great amount known about all of the primary characters presented in Copenhagen; the following includes those bits of information which are directly relevant and referenced in the work itself.[2]
Werner Heisenberg was born in 1901, in Würzburg, Germany. The son of a university professor, Heisenberg grew up in an environment with an intense emphasis on academics, but was exposed to the destruction that World War I dealt to Germany at a rather young age. He married Elisabeth Schumacher, also the child of a professor, and they had seven children. He received his doctorate in 1923 from the physicist Arnold Sommerfeld, and went to Copenhagen to study quantum mechanics with Niels Bohr in 1924, when he was 22, and replaced Bohr's assistant, H. A. Kramers. In 1926, The University of Leipzig offered Heisenberg the opportunity to become Germany's youngest full professor. He is best known for his "Uncertainty Principle", (translated from the German Ungenauigkeit [inexactness] or Unschärfe [lack of sharpness] Relation, which was later changed to Unbestimmtheit meaning "indeterminacy".) In 1927, he and Bohr presented the Copenhagen interpretation of quantum mechanics. During the Second World War, Heisenberg worked for Germany, researching atomic technology and heading their nuclear reactor program. After the war, his involvement with the Nazis earned him certain notoriety in the world of physicists, mainly due to the fact that he could have given Germany the means to produce and use nuclear arms. He continued his research until his death in 1976 in Munich.
Niels Bohr was born in 1885, making him 38 when Heisenberg first came to work with him. He married Margrethe Norlund in 1912 in Copenhagen and together they had six sons, two of whom died while young. Biographer Harry Lustig notes that "Most of the world's great theoretical physicists... spent periods of their lives at Bohr's Institute." Before the war, his research was instrumental in nuclear research, some of which led to the building of the atomic bomb. During the war, however, Bohr was living in occupied Denmark and somewhat restricted in his research; he escaped to Sweden in 1943, just before an SS sweep which would have targeted him through his Jewish heritage. In the US, he worked in Los Alamos on the atomic bomb until the end of the war. He died in 1962 and was survived by his wife, Margrethe.
Margrethe Bohr, known later in her life as Dronning or "Queen" Margrethe, was born in 1890 in Denmark. She was closely involved in her husband's work; he would commonly bounce ideas off her, trying to explain them in "plain language". She died in 1984, survived by several of her children. Her son Hans wrote, "My mother was the natural and indispensable centre. Father knew how much mother meant to him and never missed an opportunity to show his gratitude and love.... Her opinions were his guidelines in daily affairs."
Style
The construction of the plot is non-linear, seeing as it does not exist in time and space. Sometimes one character will not notice that there are other people in the space, and speak as if to no one. The world that Frayn presents is outside of our conceptions as audience members, simply by virtue of the fact that no one attending the play has ever died. So the world in which Copenhagen is based is somewhere between heaven and an atom.
It can also be thought to exist "inside the heads" of the characters present. It is a subjective world, taking and manipulating history, picking apart some events and mashing others together to better compare them. The characters are all plagued by some form of guilt or another, particularly in reference to the atomic bomb, and they are trapped in this world, doomed to forever speculate on that evening in Copenhagen in 1941 to determine how the world might have been changed. These are all traits of the artistic style known as Expressionism.
In his preface to A Dream Play, August Strindberg notes that in these worlds, "everything is possible and probable. Time and space do not exist. Working with... real events as a background, the imagination spins out its threads of thoughts and weaves them into new patterns." Copenhagen is an embodiment of these principles.
Recurring images and motifs
Because the concepts in physics and politics are at times very complicated or very abstract, Frayn uses several controlling images to better relate certain ideas to his audience.
• Skiing and Table-Tennis – These two activities are referred to as a pastime of Bohr and Heisenberg's, and both demonstrate the competition between the two (representative of national competition.) They are also used to suggest Heisenberg's speed and recklessness which contrasts with Bohr's caution and tediousness.
• Invisible Straight – An anecdote in which Bohr managed to bluff himself in a game of poker by betting on a straight that he thought he had, but he really did not. That principle is applied to nuclear weaponry, suggesting that nations will act differently when they think that an opponent can produce nuclear arms, whether or not the opponent can.
• Cap-Pistols, Land Mines and Nuclear Reactors – These fall into the Toy vs. Weapon theme and once again presents anecdotes of Bohr and Heisenberg's lives. Their fascination in playing with the new toy blinds them to the danger that it poses.
• Bomb – The term "bomb" appears as a literal looming image in many cases, but it is used figuratively in a couple of instances, as if it should be a joke, but with such grave implications that it cannot be found funny. (For example, Heisenberg refers to a "bomb having gone off" in Bohr's head.)
• Christian Reaching for the Life-Buoy – Christian was one of Bohr's sons, who tragically drowned while he and Bohr were out sailing. The phrase "Christian reaches for the life-buoy" appears several times during the play, and every time, the characters seem to hold their breath in the hope that this time, Christian will survive. Bohr had concluded that they would have both drowned had he jumped in to save his son, which presents an idea of futile heroics, particularly with reference to Heisenberg and what should happen if he were to resist Hitler's rule.
• "Another Draft" – Whenever the characters conclude that an interpretation of their 1941 meeting is incorrect, they call for "another draft".
Language
Though the dialogue does not contradict logic, it cannot be called realistic in the strictest sense. One character's line might fade into the next as though the second person knew exactly what he was going to say; sometimes a character will slip into a memory and partially relive a former or younger self in a monologue; and over the course of the show, there is a definite ambiguity as to whether they are speaking to one another or to the audience.
The play was originally written in English, but the real people in the exchange may have had the conversation in Danish or German, but even with translation in mind, Frayn defends that the words in the script are those that the characters would actually say. In his post-script, he writes, "If this needs any justification, I can only appeal to Heisenberg himself." Understandably, Frayn needs to present the characters in an interesting and dramatic light, as well as depicting a setting that no living person has visited, so the accuracy of such dialogue is subject to dwindle by degrees.
Plain language and scientific language both operate in the play. There are several instances when the two physicists start speaking too scientifically for many people to understand, and one of them will remark that they must revert to plain language, to explain it in a way that Margrethe will understand. Even for that effort, criticism arose about the complexity of the play and the difficulty for viewers to comprehend. A writer for The Commonweal commented on the Broadway premiere, saying that "the play's relentless cerebral forays can... be frustrating."
Production history
London Premiere – 1998
Copenhagen opened in the National Theatre in London and ran for more than 300 performances, starring David Burke as Niels Bohr, Sara Kestelman as Margrethe Bohr, and Matthew Marsh as Werner Heisenberg. It was directed by Michael Blakemore.
"Copenhagen" transferred to the Duchess Theatre in London's West End, where it ran from 8 February 1999, for more than 750 performances. It had a "second" cast when it opened in the West End, who were responsible for performing at least one of the matinee shows each week. The second cast consisted of David Baron as Niels Bohr, Corinna Marlowe as Margarethe Bohr, and William Brand as Werner Heisenberg, and after six months, they replaced the original cast for the rest of the West End run.
Broadway Opening – April 2000
Continuing under the direction of Michael Blakemore, it opened on Broadway at the Royale Theatre on 11 April and ran for 326 performances. Starring Philip Bosco as Bohr, Michael Cumpsty as Heisenberg and Blair Brown as Margrethe, it went on to win the Tony Award for Best Play, along with two others for Best Featured Actress in a Play (Blair Brown), and Best Direction of a Play (Michael Blakemore). But even for its success, Frayn admitted in an article that "A number of commentators expressed misgivings about the whole enterprise." Several critics noted that it was heavy with scientific dialogue, a little too heavy for the common audience. Though a writer from Physics World hailed it as "brilliant theatre ", Charles Spencer, of The Daily Telegraph, wrote, "I felt that my brain was being stretched to breaking point—well beyond breaking point, in fact."
International Productions

A 75-minute single-act adaptation premiered on 8 December 2022 at the "K! Kültüral Performing Arts" theatre in Istanbul. Translated to Turkish and directed by Noyan Ayturan, the cast includes Umut Beşkırma as Heisenberg, Yaman Ceri as Niels Bohr, and Burcu Ger as Margrethe Bohr.[11]
The play was adapted as a television movie in 2002, with Daniel Craig as Heisenberg, Stephen Rea as Niels Bohr, and Francesca Annis as Margrethe Bohr. The movie substantially cuts down the script of the play, eliminating several recurring themes, and most of the material that established the community of scientists in Copenhagen. It also abandons the abstract staging of the theatrical version in favour of being set in the city of Copenhagen, in Bohr's old house.

Cesear's Forum, a minimalist theatre company at Playhouse Square, Cleveland, Ohio, presented the play, with Dana Hart, Mary Alice Beck and Brian Bowers, in a September/October 2019 production. Cleveland Scene's Elaine Cicora noted: "While Copenhagen's weirdness has historically drawn some grumblings from critics and audiences alike, the three-actor cast assembled here – comprising established veterans of the Cleveland theater scene – does a commendable job of illuminating the humanity inside this piece of historical fiction."[17]
The meeting took place in September 1941 when Bohr and Heisenberg were 55 and 39, respectively. Heisenberg had worked with Bohr in Copenhagen for several years starting in 1924.
Much of the initial controversy stemmed from a 1956 letter Heisenberg sent to the journalist Robert Jungk after reading the German edition of Jungk's book, Brighter than a Thousand Suns (1956). In the letter, Heisenberg said he had come to Copenhagen to discuss with Bohr his moral objections toward scientists working on nuclear weapons but how he had failed to say that clearly before the conversation came to a halt. Jungk published an extract from the letter in the Danish edition of the book in 1956 that made it appear as if Heisenberg was claiming to have sabotaged the German bomb project on moral grounds.[18] Jungk omitted a critical sentence from Heisenberg: "I would not want this remark to be misunderstood as saying that I myself engaged in resistance to Hitler. On the contrary, I have always been ashamed in the face of the men of 20 July (some of whom were friends of mine), who at that time accomplished truly serious resistance at the cost of their lives."[19]
Bohr was outraged after reading the extract in his copy of the book, feeling that it was false and that the 1941 meeting had proven to him that Heisenberg was quite happy to produce nuclear weapons for Germany. Bohr drafted a number of letters about this issue, but did not send them.[20][21]
Jungk's book was influential on Frayn's play via the work of journalist Thomas Powers, who repeated the claims that Heisenberg had sabotaged the German nuclear program in a 1993 book, further asserting that the Copenhagen meeting was actually a counterintelligence operation to let Bohr in on what the Nazis were up to.[22] Frayn's play, which portrays Powers' theory sympathetically as a possible interpretation of the meeting, brought more attention to what previously had been a primarily scholarly discussion. After the play inspired numerous scholarly and media debates over the 1941 meeting, in 2002 the Niels Bohr Archive in Copenhagen released to the public all sealed documents related to the meeting.[20] Among the documents were the unsent letters Bohr drafted to Heisenberg about Jungk's book and other topics.[23] Many historians have strongly criticised the play on the basis of the released letters, contending:[21]
Heisenberg did not know how to build a bomb, and so could not have withheld the information.
There is no evidence Heisenberg wanted Germany to lose the war, let alone secretly undermined the German war effort.
There is no evidence Heisenberg proposed some agreement between physicists to not build the bomb.
Heisenberg and Carl von Weizsäcker have been consistently dishonest about the Copenhagen meeting.
A collection of historical essays provoked by the play was published in English in 2005,[24] with the vast majority of historians disagreeing with Frayn's depiction of the events.[19] In a March 2006 interview Ivan Supek, one of Heisenberg's students and friends, commented that "Copenhagen is a bad play" and that "Frayn mixed up some things". Supek also claimed that Weizsäcker was the main figure of the meeting. Allegedly, "Heisenberg and Weizsäcker came to Bohr wearing German army uniforms. Weizsäcker tried to persuade Bohr to mediate for peace between Great Britain and Germany and Heisenberg practically completely relied on his political judgement". Supek received these details in a confidential conversation with Margrethe, who thought he would never make them public. Supek however felt it was "his duty to announce these facts so that future generations can know the truth about the Bohr – Heisenberg meeting".[25]
In a 2016 assessment by Alex Wellerstein, the nuclear historian asserts that the truth of the Copenhagen meeting is that "we’ll never know, and it probably isn’t that important in the scheme of things". Nevertheless, he argues that Frayn's play creates a false balance in ascribing undue credibility to the theory (rejected by almost all historians) that Heisenberg sabotaged the German nuclear program, a theory Heisenberg did not directly advocate (being misquoted by Jungk) but also did not publicly dispute. The play was accurate in not portraying the Nazis as narrowly failing to obtain the bomb, but there were many other far more plausible reasons for their failure. On the other hand, Wellerstein praised the play for the moral questions it raised and for creating public interest in history.[19]
Physicists referenced
Over the course of the play, a number of renowned physicists are mentioned. Many of them are referenced in the context of their work with either Bohr or Heisenberg. This is the order they appear in the script:
Aage Niels Bohr was a Danish nuclear physicist who shared the Nobel Prize in Physics in 1975 with Ben Roy Mottelson and James Rainwater "for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection". His father was Niels Bohr.
Niels Henrik David Bohr was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research.
Werner Karl Heisenberg was a German theoretical physicist, one of the main pioneers of the theory of quantum mechanics, and a principal scientist in the Nazi nuclear weapons program during World War II. He published his Umdeutung paper in 1925, a major reinterpretation of old quantum theory. In the subsequent series of papers with Max Born and Pascual Jordan, during the same year, his matrix formulation of quantum mechanics was substantially elaborated. He is known for the uncertainty principle, which he published in 1927. Heisenberg was awarded the 1932 Nobel Prize in Physics "for the creation of quantum mechanics".
Michael Frayn, FRSL is an English playwright and novelist. He is best known as the author of the farce Noises Off and the dramas Copenhagen and Democracy.
Robert Jungk was an Austrian writer, journalist, historian and peace campaigner. He wrote mostly on matters relating to nuclear weapons.
Carl Friedrich Freiherr von Weizsäcker was a German physicist and philosopher. He was the longest-living member of the team which performed nuclear research in Nazi Germany during the Second World War, under Werner Heisenberg's leadership. There is ongoing debate as to whether or not he and the other members of the team actively and willingly pursued the development of a nuclear bomb for Germany during this time.
Nazi Germany undertook several research programs relating to nuclear technology, including nuclear weapons and nuclear reactors, before and during World War II. These were variously called Uranverein or Uranprojekt. The first effort started in April 1939, just months after the discovery of nuclear fission in Berlin in December 1938, but ended only a few months later, shortly ahead of the September 1939 German invasion of Poland, for which many notable German physicists were drafted into the Wehrmacht. A second effort under the administrative purview of the Wehrmacht's Heereswaffenamt began on September 1, 1939, the day of the invasion of Poland. The program eventually expanded into three main efforts: Uranmaschine development, uranium and heavy water production, and uranium isotope separation. Eventually, the German military determined that nuclear fission would not contribute significantly to the war, and in January 1942 the Heereswaffenamt turned the program over to the Reich Research Council while continuing to fund the activity.
Operation Epsilon was the codename of a program in which Allied forces near the end of World War II detained ten German scientists who were thought to have worked on Nazi Germany's nuclear program. The scientists were captured between May 1 and June 30, 1945, as part of the Allied Alsos Mission, mainly as part of its Operation Big sweep through southwestern Germany.
Ivan Supek was a Croatian physicist, philosopher, writer, playwright, peace activist and humanist.
The Niels Bohr International Gold Medal is an international engineering award. It has been awarded since 1955 for "outstanding work by an engineer or physicist for the peaceful utilization of atomic energy". The medal is administered by the Danish Society of Engineers (Denmark) in collaboration with the Niels Bohr Institute and the Royal Danish Academy of Sciences. It was awarded 10 times between 1955 and 1982 and again in 2013. The first recipient was Niels Bohr himself who received the medal in connection with his 70th birthday.
SirMichael Willcox Perrin, CBE, FRSC was a Canadian-born British scientist who created the first practical polythene, directed the first British atomic bomb programme, and participated in the Allied intelligence of the Nazi atomic bomb.
Kernphysikalische Forschungsberichte was an internal publication of the German Uranverein, which was initiated under the Heereswaffenamt in 1939; in 1942, supervision of the Uranverein was turned over to the Reichsforschungsrat under the Reichserziehungsministerium. Reports in this publication were classified Top Secret, they had very limited distribution, and the authors were not allowed to keep copies. The reports were confiscated under the Allied Operation Alsos and sent to the United States Atomic Energy Commission for evaluation. In 1971, the reports were declassified and returned to Germany. Many of the reports are available at the Karlsruhe Nuclear Research Center and the Niels Bohr Library of the American Institute of Physics. Many of them are reprinted and transcribed in the book "Collected Works / Gesammelte Werke" listed below which is available in most libraries. There are reports numbered G-1 to G-395.
Hans Kopfermann was a German atomic and nuclear physicist. He devoted his entire career to spectroscopic investigations, and he did pioneering work in measuring nuclear spin. During World War II, he worked on the German nuclear energy project, also known as the Uranium Club.
Brighter than a Thousand Suns: A Personal History of the Atomic Scientists, by Austrian Robert Jungk, is the first published account of the Manhattan Project and the German atomic bomb project.
Copenhagen is a 2002 British television drama film written and directed by Howard Davies, and starring Daniel Craig, Stephen Rea, and Francesca Annis. It is based on Michael Frayn's 1998 Tony Award-winning three-character play of the same name.
Copenhagen is the name of East West Theatre Company's theatre production of the same name; written by Michael Frayn and directed by Nermin Hamzagic. This show is Nermin Hamzagic's first professional directorial engagement and it was soon followed by a documentary called Dreamers which was selected for screening at Sarajevo Film Festival 09 and Jihlava documentary film festival.
The Bohr family is a Danish family of scientists, scholars and amateur sportsmen. The most famous members are Niels Bohr, physicist and winner of the Nobel Prize in Physics in 1922, Aage Bohr, son of Niels, also a physicist and in 1975 also received the Nobel Prize and Harald Bohr, mathematician and brother of Niels.
Uncertainty: the Life and Science of Werner Heisenberg is a biography by David C. Cassidy documenting the life and science of Werner Heisenberg, one of the founders of quantum mechanics. The book was published in 1992 by W. H. Freeman and Company while an updated and popularized version was published in 2009 under the title Beyond Uncertainty: Heisenberg, Quantum Physics, and The Bomb. The book is named after the quantum mechanics concept known as Heisenberg's uncertainty principle. It has been reviewed many times and was generally well received.
Margrethe Nørlund Bohr was the Danish wife of and collaborator, editor and transcriber for physicist Niels Bohr who received the Nobel Prize. She also influenced her son, Nobel Prize winner Aage Bohr.
The Haigerloch Research Reactor was a German nuclear reactor test facility. It was built in a rock cellar in Hohenzollerischen Lande Haigerlochearly in 1945 as part of the German nuclear program during World War II.
