Herbert Eugene Ives (1882-1953), US engineer and physicist. Ives worked on early facsimile (fax) and television systems. He worked for the American Telephone and Telegraph Company, demonstrating long-distance television transmission in the 1920s, and pioneering television-telephone (videotelephony) systems in the 1930s. Ives is also known for his work in physics, testing Einstein's special relativity with the Ives-Stilwell experiment of 1938. Intended to disprove special relativity, the experiment confirmed the time dilation effect. This photograph, dating from 1913, is from the Bain News Service, one of the USA's earliest news picture libraries.
