Atanasoff invented the first electronic digital computer in the 1930s at Iowa State College. Challenges to his claim were resolved in 1973 when the Honeywell v. Sperry Rand lawsuit ruled that Atanasoff was the inventor of the computer.^[1][2][3][4] His special-purpose machine has come to be called the Atanasoff–Berry Computer.
