Jean Piaget was born on 9 August, 1896 in Neuchatel, Switzerland. Jean Piaget was a precocious child, having published his first article on an albino sparrow at the age of 11. This brief study is considered the beginning of his brilliant scientific career. On Saturday, Jean Piaget worked for free at the Natural History Museum. Jean Piaget attended the University of Neuchatel, where he studied Biology and Philosophy. He received his Ph.D. in Biology in 1918 at the age of 22. In 1919, Jean Piaget moved to France, where he was invited to work in the laboratory of Alfred Binet, a famous child psychologist, who developed standardized intelligence tests for children. Jean Piaget noted that the French children of the same age made mistakes like these tests and concluded that logical thinking develops gradually.
The year 1919 was a milestone in his life. Jean Piaget began his experimental studies on the human mind and also started researching on the development of cognitive skills. His knowledge of Biology led him to see the cognitive development of a child as a gradual evolution. Jean Piaget died in Geneva in 16 September, 1980.
