Hugh Everett III (/ˈɛvərɪt/; November 11, 1930 – July 19, 1982) was an American physicist who, in his 1957 PhD thesis, proposed what is now known as the many-worlds interpretation (MWI) of quantum mechanics.

In danger of losing his draft deferment, Everett took a research job with the Pentagon the year before completing the oral exam for his PhD and did not continue research in theoretical physics after his graduation.^[4] Afterward, he developed the use of generalized Lagrange multipliers for operations research and applied this commercially as a defense analyst and a consultant. He died at the age of 51 in 1982. He is the father of musician Mark Oliver Everett.

Although largely disregarded until near the end of Everett's lifetime, the MWI received more credibility with the discovery of quantum decoherence in the 1970s and has received increased attention in recent decades, becoming one of the mainstream interpretations of quantum mechanics alongside Copenhagen, pilot wave theories, and consistent histories.
