Gabriel Lippmann (1845-1921) invented a proces of colour photography. It was in 1866 that Lippmann's lectures first started to pay reference to the posibility of colour photography. Lippmann worked on the principle that light reflected from a flat plate would produce interference planes at specific distances from the surface depending on the frequency set. By 1893 the first orthochromatic colour photograph had been produced. Lippmann was awarded a Nobel prize in 1908.
