German architect and structural engineer Frei Otto (31 May 1925 – 9 March 2015) was well known for his pioneering innovations in lightweight and tensile structures. Shortly before his death in 2015 he was awarded the Pritzker Prize and prior to that he was awarded the RIBA Royal Gold Medal in 2006. Much of his research in lightweight structures is as relevant today as when he first proposed them over 60 years ago, and his work continues to inform architects and engineers to this day.
Frei Otto: The Latest Architecture and News
The Pritzker Prize is the most important award in the field of architecture, awarded to a living architect whose built work "has produced consistent and significant contributions to humanity through the art of architecture." The Prize rewards individuals, not entire offices, as took place in 2000 (when the jury selected Rem Koolhaas instead of his firm OMA) or in 2016 (with Alejandro Aravena selected instead of Elemental); however, the prize can also be awarded to multiple individuals working together, as took place in 2001 (Herzog & de Meuron), 2010 (Kazuyo Sejima and Ryue Nishizawa of SANAA), and 2017 (Rafael Aranda, Carme Pigem, and Ramon Vilalta of RCR Arquitectes).
Historically inspired by some of the first man-made shelters—such as the black tents first developed using camel leather by the nomads of the Sahara Desert, Saudi Arabia, and Iran, as well as the structures used by Native American tribes—tensile structures offer a range of positive benefits compared to other structural models.
Tensile structure is the term usually used to refer to the construction of roofs using a membrane held in place on steel cables. Their main characteristics are the way in which they work under stress tensile, their ease of pre-fabrication, their ability to cover large spans, and their malleability. This structural system calls for a small amount of material thanks to the use of thin canvases, which when stretched using steel cables, create surfaces capable of overcoming the forces imposed upon them.
Frei Otto (1925-2015) was best known for his innovative lightweight structures, even naming an institute after them at the Stuttgart Technical University. His speciality in tension and membrane structures were, and still are, not only beautiful, but also incredibly modern for his time, creating forms that were entirely new to the eye. One of his most notable creations is the Multihalle, which he contributed towards with the architects Carlfried Mutschler + Partner in 1975; it still remains the largest freestanding wooden lattice structure in the world.
Following the award of the Pritzker Prize to Otto shortly before his death in 2015, the ZKM Center for Art and Media in Karlsruhe is hosting an exhibition of his works in order to introduce "new perspectives on the work of Frei Otto" while "formulating present-day questions concerning the future of our built environment." In service of this aim, architects FAR frohn&rojas created an exhibition design both reminiscent of Otto's deceptively simple structures, and carefully calibrated to show the huge archive of work to great effect. Read on to find out more about the exhibition and its design.
Frei Otto: Spanning the Future, a documentary focusing on the life and work of 2015 Pritzker Prize winner, Frei Otto, has finished production and will be screened at various venues during the course of 2016. The film features one of the last interviews Otto gave before his death, in addition to commentary from renowned architects and engineers, including Zaha Hadid and Jürgen Hennicke, on the importance of his work. In the film, Otto discusses the influences on his work and his approaches on form finding and the development of tensile structures.
In March of this year, two of the world’s great architects died in the same week. The coincidence was unusual not because of the similarities between these two men - the advanced stage of their careers, their age and relative success - but because of the marked differences. In the few days between their mutual passing, one of the two was awarded architecture’s highest medal, the Pritzker Prize. This year’s winner, Frei Otto, had been notified of his triumph in the months prior to his death. Someone you might call his alter ego – stylistically that is – the late, great Michael Graves, died shortly after the prize was awarded to Otto.
Otto was a leading light of a particular strain of European modernism, whose most lauded works were mainly completed in his youth; on the other side of the pond, Michael Graves ran a busy commercial practice with more than 350 completed buildings, but was reviled by some for his revisionist, classical style.
Tonight the Pritzker Prize will hold its annual award ceremony, this year honoring the work of 2015 laureate Frei Otto, who sadly passed away the day before he was announced as this year's winner on March 10th. This year, the ceremony will be hosted in Miami Beach at Frank Gehry's New World Center, the first time the ceremony has been held in the Miami Area. Speakers will include Tom Pritzker and Chair of the Jury, Lord Peter Palumbo, alongside a selection of past Pritzker Laureates.
uncube has published an entire issue dedicated to the late Frei Otto. The architect and inventor, known best for his tensile structures, was the first ever to be awarded the Pritzker Prize posthumously. Honoring Otto with more than a "simple retrospective homage," uncube has compiled an extensive online issue of "thoughts, anecdotes and observations" that reflect Otto's legacy and the ideas that lead him to be a significant part of architectural history. View the entire uncube issue on Frei Otto, here.
Pritzker laureate Frei Otto was best known for his tensile structures. A prime example Otto’s ingenuity, the 1972 Olympic Stadium in Munich was a collaborative work with Gunther Behnisch that connected the park’s main programs - the natatorium, gymnasium and main stadium - with a whimsical, lightweight canopy structure that mimicked the “rhythmic protrusions” of the Swiss Alps. Watch the Spirit of Space short film above to see the project in its current state and learn more about the pioneering structure, here.
After news of Frei Otto winning the 2015 Pritzker Prize broke, the internet was filled with comments on his influence on the profession over the past half a century of architecture. Of course, with the news of the Pritzker sadly packaged with news of his death, the impulse for many to offer some words in remembrance heightened the outpouring of opinion.
In addition, Otto was especially popular among some of architecture's most established names; in a tweet, the New York Times architecture critic Michael Kimmelman revealed that among the prominent advocates pushing for him to be awarded the prize were past laureates Renzo Piano and Shigeru Ban. With that in mind, we collected the thoughts and reactions of some of the leading architects today, revealing the respect held for Otto within the profession.
In their notes on the selection of Frei Otto as the 2015 Pritzker Prize Laureate, the jury described him as an architect that took his work beyond the boundaries of the discipline, as an architect who was also a “researcher, inventor, form-finder, engineer, builder, teacher, collaborator, environmentalist, [and] humanist.”
To learn more about Otto’s multidisciplinary approach to architecture as well as his emphasis on experimentation, we turned to an interview he did with Juan María Songel in 2004, published in the book A Conversation with Frei Otto. In the interview, Otto discusses numerous topics of interest and relevance to architecture in the 21st century, and in particular the importance of experimentation and research, declaring: “Productive research must be brave!”
“The computer can only calculate what is already conceptually inside of it; you can only find what you look for in computers. Nevertheless, you can find what you haven’t searched for with free experimentation.” - From A Conversation with Frei Otto, by Juan Maria Songel
For Frei Otto, experimentation with models and maquettes was a fundamental part of his work as an architect. In 1961, he began to conduct a series of experiments with soap bubbles (featured in the video above). His experiments centered on suspending soap film and dropping a looped string into it to form a perfect circle. By then trying to pull the string out a minimal surface was created. It was these created surfaces that Otto experimented with.
Through these types of experimentation he was able to build forms and structures that were previously believed to be impossible. “Now it can be calculated, but for more than 40 years it was impossible to calculate it. I have not waited for it to be calculated in order to build it.”
“Frei Otto: Spanning the Future,” a documentary profiling the internationally renowned architect and engineer Frei Otto, has been in production since 2012. Otto, who was named the 2015 Pritzker Prize laureate on Tuesday evening (following his death on Monday night), first gained international recognition half a century ago as a pioneer in designing tensile structures using metal frames and lightweight membranes.
Frei Otto passed away this past Monday, a day before being internationally celebrated as the Pritzker Prize’s 40th laureate. The first architect to ever receive the Prize posthumously, Otto was a brilliant inventor, architect and engineer who pioneered some of history’s most ambitious tensile structures.
In honor of his legacy, we’ve complied 12 fascinating facts about Otto’s life that influenced his career and shaped the profession. Read them all, after the break.
On Tuesday evening the Pritzker Prize jury named Frei Otto as the 40th recipient of the award, making him the second German to receive the award and the first winner to receive it posthumously. Otto was both an architect and a structural engineer, perhaps best known for the 1972 Munich Olympic Stadium.
With regards to their decision the jury highlighted Otto’s “visionary ideas, inquiring mind, belief in freely sharing knowledge and inventions, his collaborative spirit and concern for the careful use of resources.”

The sudden and unexpected announcement of the Pritzker Prize yesterday evening sent shockwaves through the architecture world. With the sad death of the Prize's latest laureate Frei Otto on Monday, the Pritzker made the unprecedented decision to announce the winner two weeks early, ensuring that Otto's final, crowning achievement would make its way into the obituaries of this great man.
Of course, despite the sudden nature of the announcement, the many critics on Twitter were on hand to lend their initial thoughts in what was an interesting mix of congratulations, sadness and nostalgia. Read on after the break for all the reactions.
Frei Otto has just been named the 40th recipient of the Pritzker Prize - two weeks prior to the expected official announcement. The abrupt news has been released early due the unfortunate passing of the German architect and structural engineer, who was best known for the 1972 Munich Olympic Stadium. The pioneering tensile structure, which stood in considerable contrast to the strict, authoritarian stadium that was its predecessor, was meant to present a different, more compassionate face for Germany.
"Throughout his life, Frei Otto has produced imaginative, fresh, unprecedented spaces and constructions. He has also created knowledge. Herein resides his deep influence: not in forms to be copied, but through the paths that have been opened by his research and discoveries," says the Jury.
"His contributions to the field of architecture are not only skilled and talented, but also generous. For his visionary ideas, inquiring mind, belief in freely sharing knowledge and inventions, his collaborative spirit and concern for the careful use of resources, the 2015 Pritzker Architecture Prize is awarded to Frei Otto."
Though he sadly passed away before the award ceremony, Otto was informed of his win by the Pritzker Prize's Executive Director Martha Thorne, who traveled to his home in Warmbronn to inform him of his prize. Speaking shortly after her visit, he said: "I am now so happy to receive this Pritzker Prize and I thank the jury and the Pritzker family very much. I have never done anything to gain this prize. My architectural drive was to design new types of buildings to help poor people especially following natural disasters and catastrophes... You have here a happy man."

Last night German architect Frei Otto was selected as the 2015 Pritzker Prize Laureate, the second German to win the award and the first to receive the award posthumously. The video above shows the impressive construction process of Otto’s German Pavilion at the 1967 International and Universal Exposition in Montreal (although unfortunately without sound).
Covering an area of 8,000 square meters, the pavilion featured a large, steel mesh web suspended over eight steel masts, which were located at irregular intervals and supported by anchored cables located outside of the structure. A transparent polyester fabric was then placed over the mesh roof, creating a tent. The whole construction took only six weeks.
