Åström's 1965 paper's own Notes section places it in a Bellman–Fel'dbaum–Pontryagin–Kolmogorov control-theory lineage, directly citing A.A. Fel'dbaum's 1962 paper

Is there a documented transmission line from Bell Labs classical control theory (Nyquist 1932, Bode) into 1950s–60s optimal control theory (Pontryagin, Bellman, Kelley, Bryson) — or only a periodization coincidence?

Two independent control-theory historians trace optimal control's mathematical root to Lagrange and Hamilton, not Nyquist and Bode

Kalman's 1960 Moscow paper, not a Pontryagin/Bellman/Kelley/Bryson citation line, is the documented bridge between classical and optimal control

Rufus Isaacs's RAND research is credited with precursors of the maximum principle five years before Pontryagin — and RAND itself is an unrecognized bridge between the vault's Nash and Blackwell notes

Rufus Isaacs's first RAND paper (1951) already contained precursors of the maximum principle, dynamic programming, and backward analysis — five years before Pontryagin's 1956 announcement

Chen et al. (2018), 'Neural Ordinary Differential Equations,' cite Pontryagin by name for the adjoint sensitivity method and equate it with reverse-mode automatic differentiation / backpropagation

Does Pontryagin's 1956 maximum-principle announcement genuinely predate Kelley (1960) as an independent Cold War discovery, and did Boltyanskii/Gamkrelidze/Mishchenko's 1956 work already contain the co-state/adjoint backward-gradient equation?

The vault's exemplar blind mathematician, Pontryagin, is an unacknowledged root of backpropagation's optimal-control ancestry
