The Conjugate Gradient method was also invented in the 1950s, with independent developments by Cornelius Lanczos, Magnus Hestenes and Eduard Stiefel, but its nature and applicability were misunderstood at the time.
Hestenes, Stiefel, and Lanczos, all from the Institute for Numerical Analysis at the National Bureau of Standards, initiate the development of Krylov subspace iteration methods.

The LR algorithm was developed in the early 1950s by Heinz Rutishauer, who worked at that time as a research assistant of Eduard Stiefel at ETH Zurich.
