Some famous CIEAEM members and their testimonies

Caleb Gattegno

A brief summary
The mathematician, pedagogue and philosopher Caleb Gattegno, University of London, is the spiritus rector of CIEAEM in its foundation. But there were two very distinguished personalities at the beginning who directed and determined the work of CIEAEM in the first ten years: the French Gustave Choquet (President), the Swiss psychologist and cognition theorist Jean Piaget (Vice-president) supported by Caleb Gattegno as secretary. Choquet brought into the discussion the ideas of a reform guided by the restructured new "architecture" of mathematics, Piaget presented his famous results of research in cognition and conveyed new insights into the relationships between mental-cognitive operative structures and the scientific development of mathematics, Gattegno attempted to connect the new mathematical meta-theory to psychological research by a philosophical and pedagogical synthesis and to create and establish relationships with mathematics education as an important part of general education.
