Benjamin Franklin

Some sources claim that Benjamin Franklin slept 2-4 hours a night.
Though we all know his famous quote: "Early to bed, early to rise, makes a man healthy, wealthy, and wise."Actually, Franklin’s reputation regarding limiting sleep is closely akin to his reputation for frugality – "A penny saved is a penny earned," and all that. Sleep is something that is natural, but has the potential for being misused. (Too much of a good thing, in other words.) In Franklin’s day, industriousness and hard work were extremely important human virtues. Edison adopted Franklin’s philosophy as well, and in both cases, it was important for them to model their behavior in a way that suggested that they didn’t sleep very much. To them, it meant that they were diligent and demanding in their lives, and never lazy in any way. In Franklin’s autobiography, he explains his quest (tongue-in-cheek) for moral perfection. In his principles for order, Franklin offered appropriate activities for each hour of the day. In his thesis, Franklin allocated only 4 hours of sleep per night. This tenet is the most often quoted reference to the myth of Franklin’s lack of sleep.
"There will be sleeping enough in the grave."~ Benjamin FranklinFranklin “caught up” on his sleep, logging many hours “in the sack” after bouts of sleepless activity.
