Logo was the first computer language designed for children. It became a banner for changing the way we think about children as learners. They could design, create and debug projects based on their own procedural thinking. They also saw themselves as teachers as they taught computers how to do things. I was part of the initial design team shaping Logo for learning and teaching. Another factor in Logo’s history was that its growth took place in research labs focused on making machines think like humans. My chief mentors were Seymour Papert and Marvin Minsky, then co-directors of the MIT Artificial Intelligence Lab. My work was continually enhanced by their contributions as together we gave breadth and depth to the Logo Computer Culture.
