Truly a Hero! I owe him a great deal!
I got my real start in Computers and Programming due to Logo. I was lucky enough to get a high school co-op placement at Ottawa's Carleton Board of Education's Computer Pilot Project, the Computer P.L.A.C.E. where I got to play with a Terrapin floor turtle, and ended up having to hack it's code fix it's programming to make it draw square "squares". I taught computer programming using LOGO, both Terrapin and Apple versions, to some of the very same high school teachers who had told me that I couldn't do programming because my math wasn't good enough. It also enabled me to get a summer job teaching at a computer day camp, and thus my career in computers was launched!
This Samhain, Seymour Papert, you will remembered among the honoured ancestors of my craft! Hail and Farewell!
