Raimund Abraham and Walter Pichler were key figures in Austria's radical architectural movement during the 1960s. Like their counterparts in groups such as Archigram in Britain and the Metabolists in Japan, they were concerned with the space-age ideal of a portable, self-sustaining architectural environment. Also influenced by a Viennese tradition in which architecture is closely aligned with sculpture, they often designed buildings with monumental, highly symbolic, geometric forms.

Abraham and Pichler collaborated on a number of projects while living and working in Vienna from 1960 to 1964. Much of their work together conveys the experimental spirit of architectural drawing of the 1960s.

Born in 1933 in Lienz, Austria, Abraham studied architecture at the Polytechnic in Graz. His Elementare Architektur was published in 1963, and is considered to be a key text for the Austrian radical movement.

Also native to Austria, Pichler has worked as a painter and sculptor for the last three decades. In 1968 he captured the world's attention with Prototypes — models for objects that were intended to be serially produced — which, in turn, influenced the designs of architects like Coop Himmelblau and Haus-Rucker-Co.
