Gunpei Yokoi, you certainly do not know this name, but your childhood have been shaped by his inventions. Indeed, Yokoi is the inventor of the Game Boy, and D-pad, the multi controller found on all joysticks.
Before inventing the first portable game console and one of the most important pieces of the video game technology that revolutionized that sector, Gunpei Yokoi was responsible for the maintenance and the upkeep of the machines used to manufacture the Hanafuda cards (a traditional Japanese card game) in Nintendo.
Yokoi began creating toys in his spare time and in 1966, the Nintendo President Hiroshi Yamauchi, saw his inventions by chance in the factory where he worked and that was the turning point in the career of the maintenance man.
Gunpei Yokoi quickly worked his way up the ranks in the Japanese company. Not only did he invent the Game Boy but he was also behind the creation of the superhuman abilities of Mario, one of the most iconic characters of video games, and the emergence of the multi-player mode in this game after introducing his brother; Luigi.
