Herbert Eugene Ives (July 21, 1882, Philadelphia, Pennsylvania – November 13, 1953) was a scientist and engineer who headed the development of facsimile and television systems at AT&T in the first half of the twentieth century.
Ives studied at the University of Pennsylvania and the Johns Hopkins University, where he graduated in 1908. He wrote a 1920 book on aerial photography, while an Army reserve officer, in the aviation section. Ives was also an avid coin collector, and was President of the American Numismatic Society. He was president of the Optical Society of America from 1924 to 1925 and was awarded the Frederic Ives Medal in 1937.
Like his father Frederic Eugene Ives, Herbert was an expert on color photography. In 1924, he transmitted and reconstructed the first color facsimile, using color separations. In 1927, he demonstrated 185-line long-distance television, transmitting the image of then-Secretary of Commerce Herbert Hoover from AT&T's experimental station 3XN in Whippany, New Jersey.
In the 1940s, Ives expressed his opposition to Einstein's theory of relativity and argued that Einstein's derivation of the mass-energy relation was invalid.  Ives asserted in many of his writings that the predictions of special relativity were wrong, and he also argued against what he regarded as "the indeterminancies and impotences by which the "Restricted Theory of Relativity" has been widely publicized".
Ives espoused an ether-based view of physics, somewhat similar to that of Lorentz, although unlike Lorentz, Ives maintained that this view contradicted Einstein's special relativity. Ives attempted to demonstrate the correctness of his ether-based views and to refute special relativity by means of logical arguments and experiments. He is best known for the Ives–Stilwell experiment, which ironically provided direct confirmation of special relativity's time dilation factor, although Ives himself denied that the results were consistent with special relativity. This paradoxical aspect of Ives's work was described by his friend, the noted physicist H. P. Robertson, who contributed the following summary of Ives's attitude toward special relativity in a biography of Ives:
