No mention of Walter Wriston and First National City Bank (later Citicorp)? Wriston is sometimes credited with the concept of networked ATMs, in the sense that he as an executive pushed the project forward.[1] He scaled up the technology, flooding New York City with ATMs. Then everybody else in banking had to install them.
