 In discussion with Tukey, Richard Garwin recognized the general applicability of the algorithm not just to national security problems, but also to a wide range of problems including one of immediate interest to him, determining the periodicities of the spin orientations in a 3-D crystal of Helium-3.Garwin gave Tukey's idea to Cooley (both worked at IBM's Watson labs) for implementation.Cooley and Tukey published the paper in a relatively short time of six months.
