Arthur Joseph Hungerford Pollen

Arthur Joseph Hungerford Pollen was an English journalist, businessman, and commentator on naval affairs who devised a new computerised fire-control system for use on battleships prior to the First World War. His most important technical innovation was one of the world's first electrically-powered analogue computers, patented as the Argo Clock: a differential analyser which enabled big guns to engage with long-range targets when both ships were moving at speed in different directions.
