The Jean Piaget Archives sadly announces the death of Professor Leslie Smith on 29 December 2020.
Les Smith, as he was known by his friends and colleagues, was Emeritus Professor at the University of Lancaster, United Kingdom. With a philosophical background, he made a major contribution to the diffusion and expansion of the constructivist approach of Jean Piaget and the School of Geneva. He was particularly interested in the problem of the emergence of necessary and atemporal knowledge, which he considered from an epistemological, logical and historical point of view. He was also deeply involved with the English translations of the works of Jean Piaget, highlighting the deontological necessity of translating them in accordance with the spirit of the text.
