Frank Rosenblatt

Inventor of the perceptron (1957–62) and the figure the Minsky–Papert Perceptrons (1969) is written against — the pivot of the vault's "did-the-book-kill-connectionism" myth-ledger thread. A second, stranger thread makes him a bridge rather than a footnote: in 1966 he ran experiments on molecular memory transfer in rats, tying the perceptron pioneer to the short-lived neuroscience of "memory as transferable substance." Dreyfus later counted the connectionist line Rosenblatt started as vindicated, not the target of his AI critique.
