Multics? CTSS? OS/360 had hierarchical names ca. 1964/5, although much might depend on the interpretation of `appear', given that system's troubled early history, and i recall someone telling me the implementation was unusual. Several groups seemed to be implementing them about the same time. None of my old books mention who suggested it first, or indeed when Microsoft first got the patent. I've got some more old books at the office, though.
