Franklin realized that waking up closer to sunrise gave him more hours of daylight to light his home and helped him save energy, as he used fewer smoky and expensive candles.The second was George Bernard Hudson in late 19th-century New Zealand.
Hudson was an entomologist and astronomer who proposed the idea of moving clocks forward to the Wellington Philosophical Society.The third person was William Willett in early 20th-century United Kingdom.
