The M.B. or Bachelor of Medicine was the first medical degree to be granted in the United States and Canada.
In the late twentieth and early twenty-first century, other professions, particularly in clinical fields, transitioned their professional degrees to doctorates, following the example of the M.D. and J.D. In the 1990s there was also some debate in the architectural community about renaming the professional degree in architecture a "doctorate" [REF].
