Alexey Pajitnov

Alexey Leonidovich Pajitnov (born April 16, 1955) is a Russian-American computer engineer and video game designer. He is best known for creating, designing, and developing Tetris in 1985 while working at the Dorodnitsyn Computing Centre under the Academy of Sciences of the Soviet Union (now the Russian Academy of Sciences). After Tetris was released internationally in 1987, he released a sequel in 1989, entitled Welltris.

In 1991, he moved to the United States and later became a U.S. citizen. In 1996, Pajitnov founded The Tetris Company alongside Dutch video game designer Henk Rogers. Despite the game's high popularity, Pajitnov did not receive royalties from Tetris prior to this time; the Soviet Union had disintegrated by 1991.
