Does "massive rejection of person and work" refer to...?

Does "massive rejection of person and work" refer to "massive rejection of the original author and his work (in this case, "massive rejection of Adler and his work)"?

Context:

Use of Adler’s work without attribution[edit]
Much of Adler’s theories have been absorbed into modern psychology without attribution. Psychohistorian Henri F. Ellenberger writes, “It would not be easy to find another author from which so much has been borrowed on all sides without acknowledgement than Alfred Adler.” Ellenberger posits several theories for “the discrepancy between greatness of achievement, massive rejection of person and work, and wide-scale, quiet plagiarism…” These include Adler’s “imperfect” style of writing and demeanor, his “capacity to create a new obviousness,” and his lack of a large and well organized following.[55]
A prime modern example of use of Adlerian theory without attribution can be found in the work of American psychologist, Dr. Kevin Leman. Although himself a member of the North American Society of Adlerian Psychology, Leman’s self-help book on early memory interpretation only cites Adler for coining the term, “private logic,” and neglects to mention that the entire premise for his (Leman’s) book—the theory and practice of early memory interpretation—originates with Adlerian Individual Psychology.[56]
