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?

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

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?

Bell Labs classical control theory (Nyquist, Bode) may be the direct mathematical ancestor of the 1950s–60s optimal-control lineage the vault credits as backpropagation's precursor — but no source read so far states the transmission explicitly

Kelley (1960) and Bryson (1961) computed gradients through multi-stage systems by backward chain-rule iteration — a precursor lacking backpropagation's sparsity efficiencies
