IASS Torroja Medalists

The Eduardo Torroja MedalThe Torroja Medal was established by the Executive Council of 1971 to promote the aims and objectives of the Association to the world body of engineers and architects. The engraved medal represents the highest individual recognition given by the Association to members or nonmembers of the Association in recognition of outstanding and distinguished contributions to design, construction or research of shell and/or spatial structures. It is conferred upon those who embody the ideals and accomplishments of Eduardo Torroja.

The Torroja Medal is named in honor of the Founding President of the IASS, Professor Eduardo Torroja (Spain, 1899-1961), one of the world's great structural engineers.  Each of his works, from a humble chapel hidden in the mountains to the well-known and masterpiece structures of the Algeciras Market and the Madrid Racecourse Tribune, shows a lesson of originality and simplicity based on the knowledge of the way structures work and the possibilities of the "new materials" of his era, such as reinforced and prestressed concrete. Torroja was also a humanist, a great teacher, a manager of several companies and testing laboratories, and a pioneering researcher.
