Frei Otto receives the 2015 Pritzker Architecture Prize, the news was released two weeks prior to the expected official announcement due the unfortunate passing of the visionary architect, 89. Frei Otto died in his native Germany on March 9, 2015.

Yesterday we gave this abrupt news.- Frei Otto has received the 2015 Pritzker Architecture Prize, Tom Pritzker announced today. Mr. Pritzker is Chairman and President of The Hyatt Foundation, which sponsors the prize. Mr. Pritzker said:

“Our jury was clear that, in their view, Frei Otto’s career is a model for generations of architects and his influence will continue to be felt. The news of his passing is very sad, unprecedented in the history of the prize. We are grateful that the jury awarded him the prize while he was alive. Fortunately, after the jury decision, representatives of the prize traveled to Mr. Otto’s home and were able to meet with Mr. Otto to share the news with him. At this year’s Pritzker Prize award ceremony in Miami on May 15 we will celebrate his life and timeless work.”

Otto was an architect, visionary, utopian, ecologist, pioneer of lightweight materials, protector of natural resources and a generous collaborator with architects, engineers, and biologists, among others.

Mr. Otto becomes the 40th laureate of the Pritzker Prize and the second laureate from Germany. 

The Jury of the Pritzker Architecture Prize selected Mr. Otto as the laureate earlier this year, and shortly thereafter the Executive Director of the prize traveled to Otto’s home and studio in Warmbronn, Germany, near Stuttgart, to deliver the news in person.

Learning that he had received the Pritzker Prize, Mr. Otto 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. So what shall be better for me than to win this prize? I will use whatever time is left to me to keep doing what I have been doing, which is to help humanity. You have here a happy man.”

Mr. Otto practiced a holistic and collaborative approach to architecture, working with environmentalists, biologists, engineers, philosophers, historians, naturalists, artists, and other architects. A distinguished teacher and author, Otto pioneered the use of modern lightweight tent-like structures for many uses. He was attracted to them partly for their economical and ecological values. He believed in making efficient, responsible use of materials, and that architecture should make a minimal impact on the environment. Frei Otto was a utopian who never stopped believing that architecture can make a better world for all.  

In contrast to the heavy, columned, stone and masonry architecture preferred by the National Socialists in the Germany in which he grew up — Otto’s work was lightweight, open to nature and natural light, non-hierarchical, democratic, low-cost, energy-efficient, and sometimes designed to be temporary.

He is best known for the roofing for the main sports facilities in the Munich Olympic Park for the 1972 Summer Olympics (with Behnisch + Partner and others), for the German pavilion at the 1967 International and Universal Exposition (Expo 67), the Japan Pavilion at Expo 2000 in Hannover, Germany (in 2000, with Shigeru Ban (2014 laureate of the Pritzker Architecture Prize)), a series of tent structures for German Federal Exhibitions in the 1950’s, and for his work in the Middle East.

The Chair of the jury of the Pritzker Architecture Prize, Lord Peter Palumbo, said today: “Time waits for no man. If anyone doubts this aphorism, the death yesterday of Frei Otto, a titan of modern architecture, a few weeks short of his 90th birthday, and a few short weeks before his receipt of the Pritzker Architecture Prize in Miami in May, represents a sad and striking example of this truism. His loss will be felt wherever the art of architecture is practiced the world over, for he was a universal citizen; whilst his influence will continue to gather momentum by those who are aware of it, and equally, by those who are not.

“Frei stands for Freedom, as free and as liberating as a bird in flight, swooping and soaring in elegant and joyful arcs, unrestrained by the dogma of the past, and as compelling in its economy of line and in the improbability of its engineering as it is possible to imagine, giving the marriage of form and function the invisibility of the air we breathe, and the beauty we see in Nature.”

More information

Frei Otto was born in Siegmar, Germany, on May 31, 1925, and grew up in Berlin. He died on March 9, 2015, in his natal Germany, in Stuttgart. “Frei” in German means “free”; his mother thought of the name after attending a lecture on freedom. Otto’s father and grandfather were both sculptors, and as a young student, he worked as an apprentice in stonemasonry during school holidays. For a hobby he flew and designed glider planes — this activity piqued his interest in how thin membranes stretched over light frames could respond to aerodynamic and structural forces.

When he had his university-entrance diploma in 1943, Otto signed up at once to study architecture, but he was not allowed to. Instead, he was drafted into the labor force. In September 1943, Otto was called for military service and he trained as a pilot. The pilot training was stopped at the end of 1944 and Otto became a foot soldier. In April 1945, he was captured near Nürnberg and became a prisoner of war. He stayed for two years in a prisoner of war camp near Chartres in France. There he worked as a camp architect; and he learned to build many types of structures with as little material as possible.

After the war, in 1948, Frei Otto returned to study architecture at the Technical University of Berlin. His architecture would always be a reaction to the heavy, columned buildings constructed for a supposed eternity under the Third Reich in Germany. Otto’s work, in contrast, was lightweight, open to nature, democratic, low-cost, and sometimes even temporary.

In 1950, with scholarship funds, he embarked on a study trip through the United States, where he visited the work of Frank Lloyd Wright, Erich Mendelsohn, Eero Saarinen, Ludwig Mies van der Rohe, Richard Neutra, Charles and Ray Eames, among others. During this time he also studied sociology and urban development at the University of Virginia.

In 1952, Frei Otto became a freelance architect and founded his own architectural office in Berlin. He earned a doctorate of civil engineering at the Technical University of Berlin in 1954. His dissertation Das Hangende Dach, Gestalt und Struktur (“The Suspended Roof, Form and Structure”) was published in German, Polish, Spanish and Russian. Also in 1954 he began work with “the tentmaker” Peter Stromeyer at L. Stromeyer & Co. In 1955, he designed and built (with Peter Stromeyer) three lightweight minimal temporary structures made of cotton fabric for the Bundesgartenschau (Federal Garden Exhibition) in Kassel, Germany. These were his first works to gain national recognition, in part for how they harmonized with nature.

Frei Otto pioneered the use of modern, lightweight, tent-like structures for many uses. He was attracted to them partly for their economical and ecological values. As early as the 1950s, he built complex models to test and perfect tensile shapes. Throughout his career, Otto always built physical models to determine the optimum shape of a form and to test its behavior. Engineers in his studio were early adopters of computers for structural analysis of Frei Otto’s projects, but the basic input data for these calculations came from the physical form-finding models.

In 1958, Otto founded the first of several institutions he would establish that were dedicated to lightweight structures — the Institute for Development of Lightweight Construction, a small private institute — and opened a new studio in the Zehlendorf district of Berlin. Over the next five years he taught periodically in the United States, taking on visiting professorships at Washington University, St. Louis; Yale University; University of California at Berkeley; the Massachusetts Institute of Technology; and Harvard University.

The establishment of the Biology and Building research group at the Technical University of Berlin in 1961 marked the beginning of his cooperative work between architects, engineers, and biologists. They applied their knowledge of tents, grid shells, and other lightweight structures to better understand the designs of biological structures and forms.

In 1962, Otto published the first volume of his major opus Tensile Structures: Design, Structure and Calculation of Buildings of Cables, Nets and Membranes (the second volume was published in 1966). In 1964, he became director of the newly founded Institute for Lightweight Structures (Institut für Leichte Flächentragwerke or IL) at the University of Stuttgart. IL was commissioned by the German government to conduct research in connection with the planning of the German pavilion for the 1967 International and Universal Exposition in Montreal, Canada, better known as Expo 67. The leaders of Germany chose Otto’s architecture to demonstrate the nation’s post-World War II industrial and engineering expertise and innovative technologies. The resulting German pavilion at Expo 67, created in collaboration with Rolf Gutbrod and Fritz Leonhardt, gave Frei Otto his international breakthrough as an architect and a design engineer. It's an early example of a large scale, passive solar building.

The following year, in 1968, Otto was named an Honorary Fellow of the American Institute of Architects, and IL was commissioned by Olympia Baugesellschaft in Munich to develop construction measurement models for the projected roof of the main sports stadium in the Munich Olympic Park. The project, realized in May 1972, by Günter Behnisch, Frei Otto, and Fritz Leonhardt, for that year’s Olympics, comprised a large membrane to cover the stands of the Olympic stadium, a tensile structure arena, a fabric roof over the Olympic swimming pool, and hyperbolic membrane canopies to connect the buildings and protect visitors from rain and sun.

In 1969, Otto established the Atelier (Frei Otto) Warmbronn architectural studio near Stuttgart. There Otto and his teams researched construction methods that could be highly effective with very little material. It happened that the forms of Otto’s buildings often found similar solutions to those in nature and thus resembled natural forms such as bird skulls and spider webs.

Otto wrote extensively throughout his career. His book Biology and Building was published in 1972 with a second volume the next year. Later research led Otto to write about the structural and building properties of bamboo, crustaceans, and soap bubbles. In 1994, he published Ancient Architects on structural inventions from the earliest days of building.

From 1964 to 1991, Otto was a full professor at the University of Stuttgart, and in 1991, he was named emeritus professor.

Over the years, Otto’s research teams would include philosophers, historians, naturalists and environmentalists. He is a world-renowned innovator in architecture and engineering who pioneered modern fabric roofs over tensile structures and also worked with other materials and building systems such as grid shells, bamboo, and wooden lattices. He made important advances in the use of air as a structural material and to pneumatic theory, and the development of convertible roofs. Otto made the results of the research available to other architects. He always favored collaboration in architecture.

To cite just two examples: from 1975 to 1980 Otto worked with Rolf Gutbrod and Ted Happold to build a tent-like gymnasium for the King Abdulaziz University in Jeddah, Saudi Arabia, and Otto co-designed the Japanese pavilion at the 2000 Hannover Expo with architect Shigeru Ban (who received the Pritzker Architecture Prize in 2014).

Frei Otto was recognized with his first major monographic exhibition in 1971 at the Museum of Modern Art (MoMA) in New York. (A redesign of the exhibition later traveled in 1975 and 1977 to venues in North America, Europe, Asia, and Australia). The exhibition “Natural Constructions,” which featured his work, was organized by the Institute for International Relations in Stuttgart in 1982 and shown in Goethe Institutes in approximately 80 countries.

In 1984, he became a founding member of the Special Research Project 230 “Natural constructions — lightweight construction in architecture and nature” of the German Research Foundation, which included the participation of four major universities in Germany. As the largest interdisciplinary German research project, it involved architects, engineers, biologists, behavioral scientists, paleontologists, morphologists, physicists, chaos theorists, physicians, historians, and philosophers. This project was completed in 1995.

Among numerous accolades, Frei Otto was awarded the Thomas Jefferson Prize and Medal in Architecture by the University of Virginia in 1974; the Medaille de la recherché et de la technique by the Academie d’Architecture, Paris, in 1982; the Grand Prize and gold medal by the Association of German Architects, also in 1982. He received the 1980 Aga Khan Award for Architecture (together with Rolf Gutbrod) for the conference centre in Mecca, Saudi Arabia, and the 1998 Aga Khan Award for Architecture (together with Omrania and Happold) for the Diplomatic Club in Riyadh, Saudi Arabia. He was named Honorary Fellow of the Royal Institute of British Architects, London, in 1982 and Honorary Fellow of the Institution of Structural Engineers, London, in 1986. In 1996, he received the Grand Prize of the German Association of Architects and Engineers, Berlin. In 2005, he was awarded the Royal Gold Medal of the Royal Institute of British Architects (RIBA).

On March 9, 2015, Frei Otto died in his native Germany in Stuttgart, just one day after meeting, even without being public to the world, that he gave the Pritzker Prize 2015. One day after his death the news was make public to the world, who know at the same time the loss of the renowned architect and that he was granted with the first Pritzker Architecture Prize posthumous.
