The inventor of the typewriter checked letter-pair frequency, and arranged the keyboard of his invention so that frequently used letters would not be adjacent to another. This helped to avoid the typebars of the typewriter from sticking to one another and then jamming. For example, "th" is a commonly used combination, and he wanted those two letters to lie apart from each other.
