Seymour Papert, Creator of the Logo Language, Dies At 88 (mit.edu)
New submitter gwolf writes: The great educator, creator of the Logo programming language, and the enabler for computer education in the 1980s has passed away. Listing his contributions is impossible in an article summary, but the ACM has published a short in-memoriam note for him. Papert is, without exaggeration, one of the people I owe my career and life choices to.
He was really a computing hero. He supported educating children in the field of computer science. Many of us owe a lot to him. It is a shame that most people never learn who the true heroes of computing were.
