Message from Alexander Riegler, editor of Constructivist Foundations:

Today we celebrate the centenary of Ernst von Glasersfeld who founded radical constructivism in 1974 as “an unconventional approach to the problems of knowledge and knowing. It starts from the assumption that  knowledge, no matter how it is defined, is in the heads of persons, and that the thinking subject has no alternative but to construct what he or she knows on the basis of his or her own experience.”

Ernst von Glasersfeld was born on 8 March 1917 in Munich of Austrian parents, and grew up in Northern Italy and Switzerland. Briefly studied mathematics in Zürich and Vienna. Returned to Italy in 1946, worked as a journalist, and collaborated until 1961 in Ceccato’s Scuola Operativa Italiana (language analysis and machine translation). From 1962 director of US-sponsored research project in computational linguistics. From 1970, he taught cognitive psychology at the University of Georgia, USA. Professor Emeritus in 1987. He held several honorary doctorates. Ernst von Glasersfeld passed away on 12 November 2010.
