Gunpei Yokoi
Gunpei Yokoi , sometimes transliterated as Gumpei Yokoi, was a Japanese toy maker and video game designer. As a long-time Nintendo employee, he was best known as creator of the Game & Watch handheld system, inventor of the cross-shaped Control Pad, the original designer of the Game Boy, and producer of a few long-running and critically acclaimed video game franchises such as Metroid and Kid Icarus.
Game Boy
The Game Boy is a handheld game console developed by Nintendo, launched in the Japanese home market on April 21, 1989, followed by North America later that year and other territories from 1990 onwards. Following the success of the Game & Watch single-game handhelds, Nintendo developed the Game Boy to be a portable console, with interchangeable cartridges. The concept proved highly successful, and the Game Boy line became a cultural icon of the 1990s and early 2000s.
