Voyager 2 measured the current value of Uranus's rotation, right? When was it first known? At least, that it rotated on its "side"?

Probably the first clue was the ring and moon system, which was known prior to Voyager's visit. Interestingly, in terms of the most known "natural" satellites (those which formed with the planet,and were not captured later), Uranus is king of the heap.
