Ernst Robert Fiechter (28 October 1875, in Basel – 19 April 1948, in St. Gallen) was a Swiss architect and archaeologist. He is remembered for his research of ancient Greek temple and theatre architecture. He was a cousin to psychologist Carl Gustav Jung.
He studied architecture and archaeology in Munich, obtaining his doctorate in 1904 with a dissertation on the Temple of Aphaea in Aegina. In 1906 he received his habilitation, and in 1911 was named a professor of architectural history at the Technical University of Stuttgart.[1][2]
From 1900 onward, he was engaged in educational travels to Egypt, Greece and Italy. As a professor at Stuttgart, he was involved in the restoration of many architectural structures of the local region. In connection with the 1919 opening of the Waldorf school and associated activity of theologian Friedrich Rittelmeyer, (the founder of Die Christengemeinschaft in 1922), Fiechter subsequently made the acquaintance of Rudolf Steiner, the founder of anthroposophy. Being inspired with Steiner's ideas, Fiechter became a lifelong devotee of anthroposophy.[1][2]
