Critics of the reductionism of modernism often noted the abandonment of the teaching of architectural history as a causal factor. The fact that a number of the major players in the shift away from modernism were trained at Princeton University's School of Architecture, where recourse to history continued to be a part of design training in the 1940s and 1950s, was significant. The increasing rise of interest in history had a profound impact on architectural education. History courses became more typical and regularized. With the demand for professors knowledgeable in the history of architecture, program were developed including the Advanced Masters-Level Course in the History and Theory of Architecture offered by Dalibor Vesely and Joseph Rykwert at the University of Essex in England between 1968 and 1978. It was the first of its kind.
