Knocker-upper human alarm clock - GIF

[mklotz]

In a biography of John Muir I read that he employed a janitor in his college as a knocker upper to wake him for classes. This was after his self-built mechanical alarm clock bed that ejected him at the prescribed hour was determined to be a hazard and disturbance to the other students.

I would have liked to have known him, I think.
