Pritzker Architecture Prize 2015 Frei Otto
Frei Otto was born in Siegmar, Germany, on May 31, 1925, and grew up in Berlin. “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.
