The origin of the Everettian heresy. S. Osnaghi, F. Freitas and O. Freire in Stud. Hist. Philos. Sci. B 40:97 (2009).  What the paper says!?

This paper aims to focus on the historical early developments (birth and early reception) of Everett's many-worlds interpretation. It basically suggests that the fierce, if not unreasonable and irrational, opposition from the Copenhagen school, sealed the fate of the interpretation at this time, maybe even pushed Everett away from academia. This delayed the attention and interest that the work deserved and maybe even up to now, relegated it to some curiosity when it had the potential to become mainstream. It is overall more a description of the inner tension for Wheeler to reconcile his admiration for Bohr and Everett alike, whose respective interpretations of quantum mechanics were in direct opposition. One can learn from the text the exaggerated love of Wheeler for his former teacher:

as well as his obvious admiration for his student, whom he tried to get recognized by the Copenhagen school, who despised him. The bulk is on Wheeler's obsession to have Everett's theory fit with the Bohr measurement and complementarity tenets. This was amusing to DeWitt:

Other details are interesting to note:

The origin of the Copenhagen name as an interpretation is attributed to Heisenberg in a footnote:

The Epilogue also reports interesting relations between Everett and other prominent many-worlds scientists (Deutsch is not a student of Wheeler, though):
