The Contribution of Desmond Paul Henry (1921–2004) to Twentieth-Century Computer Art

This paper describes the series of three electronic drawing machines Desmond Paul Henry constructed during the 1960s from World War II analogue bombsight computers and which, by virtue of their inspiration, idiosyncratic modus operandi and analogue-derived effects, earn Henry a place as a British computer art pioneer. The abstract graphic results of these now-defunct drawing machines are presented as precursors to digital images.
