Alexey Leonidovich Pajitnov (born 14 March 1956) is a Russian video game designer and computer engineer who developed Tetris while working for the Dorodnitsyn Computing Centre of the Soviet Academy of Sciences, a Soviet government-founded R&D center.

He only started to get royalties from his creation in 1996 when he and Henk Rogers formed The Tetris Company.

Gunpei Yokoi (横井 軍平, Yokoi Gunpei, September 10, 1941 – October 4, 1997), sometimes transliterated Gumpei Yokoi, was a Japanese video game designer.
He was a long-time Nintendo employee, 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.

Ralph Henry Baer (born Rudolf Heinrich Baer; March 8, 1922 – December 6, 2014) was a German-American inventor, game developer, and engineer.

Baers family fled Germany just before World War II and Baer served the American war effort, gaining an interest in electronics shortly thereafter. Through several jobs in the electronics industry, he was working as an engineer at Sanders Associates (now BAE Systems) in Nashua, NH, when he conceived the idea of playing games on a television screen around 1966.
With support of his employers, he worked through several prototypes until he arrived at a Brown Box that would later become the blueprint for the first home video game console, licensed by Magnavox as the Magnavox Odyssey. Baer continued to design several other consoles and computer game units, including contributing to design of the Simon electronic game. Baer continued to work in electronics until his death in 2014, with over 150 patents to his name.

Baer is considered the Father of Video Games due to his many contributions to games and helping to spark the video game industry in the latter half of the 20th century.
