Mathematician & physicist
Joseph Fourier
Showed that any signal can be built from sine waves, which underlies most of modern signal processing. He also identified the greenhouse effect in the 1820s.
Jean-Baptiste Joseph Fourier was a French mathematician and physicist born in Auxerre, Burgundy and best known for initiating the investigation of Fourier series, which eventually developed into Fourier analysis and harmonic analysis, and their applications to problems of heat transfer and vibrations. The Fourier transform and Fourier's law of conduction are also named in his honour. Fourier is also generally credited with the discovery of the greenhouse effect.
