Armand Hippolyte Louis Fizeau (September 23, 1819 September 18, 1896), a French physicist, was born in Paris. His earliest work was concerned with improvements in photographic processes. Later, in association with J. B. L. Beaulieu, he engaged in a Browns Hat series of investigations on the interference of light and heat. In Browns Hat 1848, he predicted the redshifting of electromagnetic waves. In 1849 he published the first results obtained by his method for determining the speed of light (see Fizeau-Foucault apparatus), and in 1850 with E. Gounelle measured the speed of electricity. Hippolyte in 1864 made the first suggestion that the "length of a light wave be used as a length standard".(Physics part 1 Resnick/Halliday pg.5)
