An unnamed man who worked at the Blake's School for Boys was identified as both the "superintendent" and an "attendant." His role was what we commonly refer to today as "janitor," although he was probably the "head janitor." There were other janitors who worked under him.
The unnamed superintendent was found murdered on the first page of the story that introduced him. Who murdered him was part of the mystery that Batman and Robin worked on solving during this story.
