Only in England could a lady telephone her hubby and tell him, "Yes, I got knocked up early this morning", and not risk divorce.
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.

If I remember the description from the book correctly, this one from the second link is a thermometer that works by amplifying the thermal expansion of an iron bar. He built it as a teenager. He demonstrated it at a fair and supposedly it was sensitive enough to measure the temperature change of a man standing near it.
