Armand Hippolyte Louis Fizeau (1819-1896), French physicist, was born in Paris. His earliest work was concerned with improvements in photographic processes. Later, in association with J. B. L. Foucault, he engaged in a series of investigations on the interference of light and heat. In 1848, he predicted the redshifting of electromagnetic waves.

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)

He was involved in the discovery of the Doppler's effect [cite journal

In 1853 he described the use of the capacitor (then called the "condenser") as a means to increase the efficiency of the induction coil. Subsequently he studied the thermal expansion of solids, and applied the phenomenon of interference of light to the measurement of the dilatations of crystals. He became a member of the Académie française in 1860 and of the Bureau des Longitudes in 1878. He died at Venteuil September 18, 1896.
