Such a shame. In an otherwise well-written article, the author mentions Cooley and Tukey's discovery of the FFT, but without mentioning that Gauss discovered it first, among others, each of whom approached the same idea from different directions.
The Wikipedia FFT article (https://en.wikipedia.org/wiki/Fast_Fourier_transform) credits Gauss with originating the FFT idea later expanded on by others, and correctly describes Cooley and Tukey's work as a "rediscovery."
