The East German engineer Ulrich M ther contributed an important chapter to the European history of shell construction. From 1963 on he realized pioneering shell constructions that rank among the classics of modernism and inspired architects from all over the world. The book can be understood as a classical architecture guide and furnishes a well-founded insight into the euphoric belief in progress that attended the building boom of the 1960s and 1970s. The buildings are portrayed with the aid of current photographs, plans, texts and project information.
