; 9 August 1896 – 16 September 1980) 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".
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.
Piaget was born in 1896 in Neuchâtel, in the Francophone region of Switzerland.
the couple had three children, whom Piaget studied from infancy.
From 1925 to 1929, Piaget worked as a professor of psychology, sociology, and the philosophy of science at the University of Neuchatel.
The school was run by Alfred Binet, the developer of the Binet-Simon test (later revised by Lewis Terman to become the Stanford–Binet Intelligence Scales).
Piaget assisted in the marking of Binet's intelligence tests.
In 1979 he was awarded the Balzan Prize for Social and Political Sciences.
He died in 1980 and was buried with his family in an unmarked grave in the Cimetière des Rois (Cemetery of Kings) in Geneva. The resulting theoretical frameworks are sufficiently different from each other that they have been characterized as representing different "Piagets." More recently, Jeremy Burman responded to Beilin and called for the addition of a phase before his turn to psychology: "the zeroeth Piaget." Before Piaget became a psychologist, he trained in natural history and philosophy.
