James Cooley Born

James Cooley, co-creator of the fast Fourier transform, was born. Working with John Tukey, Cooley in 1965 worked out a vast improvement to a common mathematical algorithm called the Fourier transform. Although the algorithm had been useful in computing, its complexity required too much time. While working at IBM, Cooley built on Tukey's ideas for a swifter version.
