 Abraham's poetic architectural vision was influenced by the Viennese tradition to align architecture with sculpture, and also by the Austrian physicist and philosopher Ernst Mach.Abraham theorized architecture on a "collision" course with the needs of humans, yet striving for coexistence, in a constant state of creative tension.Beginning in the late 1950s, his enigmatic architecture placed Abraham among the avant-garde, such as Hans Hollein, Walter Pichler and Günther Domenig.
