Edison is not alone in his views on sleep. He made extensive experiments with the two hundred workers in his own factory which convinced him and most of them that the majority slept much too long. The hands seem to have entered willingly into the trials: perhaps their personal regard for him influenced their conclusions. Napoleon Bonaparte and Frederick of Prussia were both satisfied with four hours of sleep,[1] while Bishop Taylor was of opinion that three hours was sufficient for any man’s needs, and Richard Baxter, who wrote “The Saints’ Rest,” thought four hours the proper measure.

Paul Leicester Ford, who was never a strong person, once told me that he found four hours’ sleep enough for all purposes. He did not wish to be understood as saying that four hours’ rest was enough, but four hours’ sleep. He was one of the few who understood the difference between sleep and rest. He frequently rested; his favorite practice being to lie back in a big armchair with a book, and forget the surrounding conditions. The book created a different set of sensations, which, combined with the pause in physical activity, brought a sense of rest to the frail body. He frequently got his four hours of sleep curled up in the big chair, and was then able to go on with the work which in a few short years made him famous. The wife of the late George T. Angell of Boston testifies that for years he seldom slept four hours a night, having found that, for him, more was unnecessary; but, of course, it does not follow that no more is necessary for anyone.
