Papert used Jean Piaget's work in his development of the Logo programming language with Wally Feurzeig, and Cynthia Solomon while at MIT. They created Logo as a tool to improve the way children think and solve problems.
Papert went on to create the Epistemology and Learning Research Group at the MIT Architecture Machine Group which later became the MIT Media Lab. Here, he was the developer of a theory on learning called Constructionism, built upon the work of Piaget in constructivist learning theories. wikipedia

Professor Emeritus Seymour Papert, pioneer of constructionist learning, dies in 2016 at 88.
