Yes, and it was a renowned job up until the late 90s/early 2000s. The job transformed drastically in the early 80s with upcoming new techniques (e.g. phototypesetting, the predecessor to digital typeset).
Without typesetters, a major role in terms of grammar and design checks broke away. This isn’t the only factor, but since early 2000s, typos where everywhere.
