IEEE gave Werbos the Neural Networks Pioneer Award in 1995 (jointly) and the Frank Rosenblatt Award in 2022 — the 2022 citation credits him with "development of backpropagation"

Both award claims, previously Wikipedia-only, now rest on IEEE's own documents (fetched and read directly at capture level):

• 1995, IEEE Neural Networks Pioneer Award — joint: "1995, Michael A. Arbib, Nils J. Nilsson and Paul J. Werbos" (IEEE Computational Intelligence Magazine, May 2006, official awardee list 1991–2006; the CIS webpage itself bot-blocks with HTTP 418, so the magazine record is the reachable Tier 1). The widely-quoted 1995 citation prose ("for the discovery of backpropagation…") appears only in Tier 2–3 retellings — [unverified-quote — needs primary] if ever load-bearing.
• 2022, IEEE Frank Rosenblatt Award — solo, verbatim from IEEE's recipients PDF: "For development of backpropagation and fundamental contributions to reinforcement learning and time series analysis." Context from the same document: Hopfield 2009, Vapnik 2012, Hinton 2014, Barto & Sutton 2026.

Why this is myth-ledger material, not just biography. IEEE's own Tier-1 award language — "development of backpropagation," under an award named for Rosenblatt — is institutional circulation of the single-inventor compression tracked at myth-werbos-invented-backpropagation. The myth entry names award citations among its circulation venues; that receipt is now verified at the primary. The accurate multi-discovery picture: claim-reverse-mode-multiple-independent-discovery, claim-linnainmaa-priority-not-paternity. The earliest documented priority sits with a Finnish master's thesis the award language silently overwrites: claim-linnainmaa-thesis-identity.
