Jean Piaget was born in Neuchantel, Switzerland on August 9, 1896 to Arthur Piaget, a professor of medieval literature, and Rebecca Jackson. He died years later in Geneva on September 16, 1980. Jean Piaget was known as one of the most significant psychologist of the twentieth century.
Jean Piaget started his studies as early as age 11 when he wrote a short paper on an albino sparrow. This paper was considered the start of his scientific career. After high school, Jean studied natural science at the University of Neuchatel, where he earned his Ph.D in 1918. One year later in 1919 he left Switzerland for France. There he spent one year working with Alfred Binet to develop the first IQ test and became interested with the incorrect answers children gave on their test. In 1921, he became director of studies at the JJ Rousseau Institute in Geneva.
