There is some debate about the appropriateness of the term 'model engineering'. Some argue that the term ' engineer ' should be reserved solely for those professionally qualified as such. However, the historic meaning of 'engineer' is one who constructs or tends engines, and as such is a fitting epithet for those who make working models as a hobby. In any case, since the term 'model engineer' was employed by 1888, the precedent for its use has long been a fait accompli.
