New Zealand scientist George Vernon Hudson and British builder William Willett proposed versions of DST in the late 1800s and early 1900s.

Franklin humorously suggested getting up earlier to save on candles but did not advocate for changing the clocks.

Many countries adopted DST during the wars to save fuel, though it was paused between the wars in Europe.
