Lord Ravleigh (John William Strutt) was an English physicist (1877 - 1919) and a Nobel Laureate (1904) who made a number of contributions to wave physics of sound and optics. (Courtesy of AIP Emilio Segrè Visual Archives. Physics Today Collection

Charles Fabry (1867-1945), left, and Alfred Perot (1863-1925),right, were the first French physicists to construct an optical cavity for interferometry (Fabry: AIP Emilio Segrè Visual Archives, E. Scott Barr Collection; Perot: The Astrophysical Journal, Vol. 64, November 1926, p.208.)



Augustin Jean Fresnel (1788 - 1827) was a French physicist, and a civil engineer for the French government, who was one of the principal proponents of the wave theory of light. He made a number of distinct contributions to optics including the well-known Fresnel lens that was used in light houses in the 19th century. He fell out with Napoleon in 1815 and was subsequently put into house-arrest until the end of Napoleon's reign. During his enforced leisure time he formulated his wave ideas of light into a mathematical theory. (Photo: Smithsonian Institution, courtesy of AIP Emilio Segrè Visual Archives.)
