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.

- 2026-08-15: Léon Bottou's own 2010 SGD paper places the Perceptron (1957) directly alongside the Widrow–Hoff Adaline (1960) in the same table as parallel members of the stochastic-gradient-descent family — a connection outside the Minsky–Papert thread this page otherwise tracks.
