Papert based his own ideas of constructionism on children's cognitive development theories of Jean Piaget, a famous Swiss psychologist with whom he worked in the 50s - early 60s.
Logo pioneered a whole class of tools and languages built around constructivist ideas (e.g. Ozobot, Scratch, EToy, Processing, Design by Numbers...) and I hope these ideas will not be totally forgotten in the era of slop, when people prize ignorance and no longer seem to appreciate the concept of "build to understand".
