Jean Piaget was a Swiss psychologist known for his work on child development. Piaget's theory of cognitive development and epistemological view are together called genetic epistemology.Piaget placed great importance on the education of children. As the Director of the International Bureau of Education, he declared in 1934 that only education is capable of saving our societies from possible collapse, whether violent, or gradual. His theory of child development is studied in pre-service education programs. Educators continue to incorporate constructivist-based strategies.Piaget created the International Center for Genetic Epistemology in Geneva in 1955 while on the faculty of the University of Geneva and directed the Center until his death in 1980.
