My favourite story about grid frequency involves Laurence Hammond, who would go on to create the Hammond organ. He was a designer of AC electric motors, and when he formed his own company, among their first products were luxury AC-powered clocks. The trouble was that they didn't keep very good time, because of fluctuations in the grid frequency.
He solved this problem by making gifts of his clocks to executives of the local power companies, and as if by magic, the timekeeping of all his clocks soon improved.
