Frei Paul Otto

Frei Paul Otto (31 May 1925 – 9 March 2015) was a German architect and structural engineer noted for his use of lightweight structures, in particular tensile and membrane structures, including the roof of the Olympic Stadium in Munich for the 1972 Summer Olympics.

Otto won the RIBA Royal Gold Medal in 2006 and was awarded the Pritzker Architecture Prize in 2015, shortly before his death.

Early life

Otto was born in Siegmar, Germany, and grew up in Berlin. He studied architecture in Berlin before being drafted into the Luftwaffe as a fighter pilot in the last years of World War II. He was interned in a POW camp near Chartres and with his aviation engineering training and lack of material and an urgent need for housing, began experimenting with tents for shelter. After the war he studied briefly in the US and visited Erich Mendelsohn, Mies van der Rohe, Richard Neutra, and Frank Lloyd Wright.

Career

He began a private practice in Germany in 1952. His saddle-shaped cable-net music pavilion at the Bundesgartenschau (Federal Garden Exposition) in Cassel brought him his first significant attention. He earned a doctorate in tensioned constructions in 1954.

Otto specialised in lightweight tensile and membrane structures, and pioneered advances in structural mathematics and civil engineering. He founded the Institute for Lightweight Structures at the University of Stuttgart in 1964 and headed the institute until his retirement as university professor. Major works include the West German Pavilion at the Montreal Expo in 1967 and the roof of the 1972 Munich Olympic Arena.

Until his death, Otto remained active as an architect and engineer, and as consultant to his protégé Mahmoud Bodo Rasch for a number of projects in the Middle East.

Otto died on 9 March 2015;
