Franklin realised that if people got up earlier, when it was lighter, they would need to use less candles.
But Franklin wasn’t the only one to propose the idea of changing the clocks.
In the UK, a builder called William Willett – who happens to be Coldplay singer Chris Martin’s great-great-grandfather – also thought it was a good idea. In 1907, he published a leaflet called The Waste of Daylight.
He was a keen golfer and wanted to encourage people to get up earlier in the day, as he was annoyed that it would get too dark in the evenings for him to carry on playing his favourite sport.
