Thomas Edison, the inventor of the light bulb, and thusly the grandfather of 24-hour gas stations and fast food restaurants, regarded sleep as a waste of time. And though he reportedly only slept 3 to 4 hours every night, he was a great proponent of the power nap.

Edison used napping to counterbalance the intensity of his work. Most days, he took one or two brief naps — on his famous cots, outdoors in the grass, and even on a chair or stool if no better option was available. Per multiple first-hand accounts, he always awoke from his naps reinvigorated rather than groggy, ready to devour the rest of the day with full alertness and zest.
Edison was born this day in 1847.
