Herbert Eugene Ives (July 21, 1882 – 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. He is best known for the 1938 Ives–Stilwell experiment, which provided direct confirmation of special relativity's time dilation., although Ives himself did not accept special relativity, and argued instead for an alternative interpretation of the experimental results.
