The Hugh Everett III Manuscript archive contains a collection of scanned original documents and audio recordings related to Hugh Everett III (November 11, 1930 – July 19, 1982), the American physicist who first proposed what has come to be known as the many-worlds interpretation (MWI) of quantum physics.
These documents include draft and final versions of Everett’s long and short Ph.D. theses and the early notes that led to these published works, Everett’s correspondence regarding his relative state formulation of pure wave mechanics, and miscellaneous biographical material. Most of these documents were discovered in the basement of Mark Everett, Hugh Everett III’s son, in Los Feliz, California by Peter Byrne in 2007 and are published here for the first time.
First published in Reviews of Modern Physics in 1957 as “The ‘Relative State’ Formulation of Quantum Mechanics,” Everett’s theory was not known as the many-worlds interpretation until 1970, and this identification was largely due to Everett’s enthusiastic supporter, physicist Bryce S. DeWitt. Today, the Everett Interpretation of quantum mechanics is one of a handful of serious contenders for explaining the structure of the quantum universe, and arguably provides the best prospects for a satisfactory resolution to the quantum measurement problem. The documents collected here describe the origin and the evolution of Everett’s own understanding of his theory.
