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 is 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):
