Dexter Wright Masters (June 15, 1909 – January 5, 1989), was an American editor and novelist who wrote extensively about the dangers of the atomic bomb.
After working for Time and Fortune magazines, he became the first editor of Tide, a marketing trade journal, age 22.
Masters co-edited with nuclear physicist Katharine Way (1903–1995) the 1946 New York Times bestseller One World or None: a Report to the Public on the Full Meaning of the Atomic Bomb.
The book included essays by Niels Bohr, Albert Einstein, and J. Robert Oppenheimer, and sold over 100,000 copies.
In the late 1950s, he was instrumental in the organization's analysis of milk samples from around the country for radiation, thus making widely available for the first time information about the fallout dangers of atmospheric nuclear tests.
