The inventor of the Game Boy, was originally Nintendo's janitor and maintenance man!
Gunpei Yokoi, a name that is unfamiliar to you, yet his inventions have shaped your childhood. Yokoi was the inventor of the Game Boy, and the D-pad. The D-pad, for those of you that don't know, is the pad of directional buttons on almost all handheld consoles, as well as video game controllers.
Before inventing one of the most important pieces of video game technology, Gunpei Yokoi was a janitor for Nintendo, and was often told to fix the machines in a factory when they were acting up. On his free time, Gunpei Yokoi would tinker on toys of his own that he could use when there wasn't anything to do at work. He spent his time doing productive things, while most of us just play solitaire on the computer when we have nothing to do at work.
By chance, in 1966, the president of Nintendo, Hiroshi Yamauchi was walking through the factory that Gunpei Yokoi worked and noticed in the corner of his eye one of Yokoi's inventions. The president ordered Gunpei to design, and make more toys in order to keep up with the demand of the Christmas rush!
Yokoi was quickly promoted through the Nintendo ranks, and soon found himself in charge of making one of the most iconic characters have superhuman abilities. That's right, not only did Yokoi invent the Game Boy, he came up with Mario's abilities, and suggested they introduce Mario's brother, Luigi.
