• Do Steinbuch & Widrow 1965 and Widrow's 1966 'Bootstrap Learning' actually document the abandoned multilayer-training attempt — and what does Widrow's oral history say about the 1985 return?

• Steinbuch & Widrow's 1965 paper is a structural comparison of two existing single-layer classifiers, not a study of multilayer network training

• Widrow's 1966 'Bootstrap Learning' paper documents a genuine, preliminary, non-gradient attempt at training multilayer networks of adaptive threshold elements

• Léon Bottou's own 2010 paper classifies the Widrow–Hoff LMS/Adaline update rule as stochastic gradient descent, matching the algorithm in the original 1960 paper

• Widrow and Hoff's own 1960 paper describes the LMS/Adaline error surface as a 'stochastic' surface, searched one training pattern at a time by steepest descent

• Widrow's 1990 retrospective (with Lehr) proves the LMS per-sample 'instantaneous gradient' is an unbiased estimate of the true gradient — the defining mathematical property of stochastic gradient descent

• Does Robert Lucky's own oral history or writing say whether he knew of Widrow-Hoff's 1960 LMS work before his 1965 equalizer paper? — his primary sources remain inaccessible; question stays unverified

• The evidence favors Lucky's 1965 equalizer as an independent invention from Widrow-Hoff LMS, but the case rests entirely on Widrow's side — Lucky's own account of awareness is still unobtained

• Widrow's own retrospectives describe Lucky's Bell Labs equalizer as an independently developed, different algorithm, with LMS entering Bell Labs' adaptive-modem work only afterward

• Madaline Rule I (1962) could adapt only the first layer of Widrow's networks — the second layer stayed fixed, making it the ceiling of pre-backpropagation multilayer training
