Jürgen Schmidhuber

Director at IDSIA; LSTM co-inventor; prolific historian-advocate of deep learning's origins (who-invented-backpropagation.html, annotated-history arXiv:2212.11279). For this vault he is primarily a WITNESS — domain-expert, Tier 2 on his own pages — whose historiography is load-bearing for the backprop-origins cluster and must be independently corroborated per the frontmatter caveat.

Did Schmidhuber's "Who Invented Backpropagation?" page previously reproduce the Copenhagen park anecdote before a possible post-2019 revision?

note
'Credit assignment' names both the sociology of scientific credit and backpropagation's technical problem — and Schmidhuber sits on the hinge

claim
Fukushima's Neocognitron (1979/1980) introduced the core CNN architecture — weight-shared local features plus downsampling — but was not trained by backpropagation

claim
Linnainmaa's 1970 thesis was a contribution to numerical analysis, not artificial intelligence

claim
Schmidhuber's 'controllers-as-weights' framing for Dreyfus 1973 is confirmed only in Schmidhuber's own words, on two of his own venues

claim
Schmidhuber's 'Annotated History of Modern AI and Deep Learning' dates the field's origin to the 1676 chain rule and circa-1800 neural nets — reading the present category back onto the deep past

claim
Myth ledger: 'Amari trained multilayer perceptrons by SGD in 1967'
