Desmond Paul Henry (1921–2004) was a Manchester University Lecturer and Reader in Philosophy (1949–82). He was one of the first British artists to experiment with machine-generated visual effects at the time of the emerging global computer art movement of the 1960s.

Each Henry drawing machine was based around an analogue bombsight computer in combination with other components which Henry happened to have acquired for his home-based workshop in Whalley Range, Manchester (O'Hanrahan 2005). Each machine took up to six weeks to construct and each drawing from between two hours to two days to complete.
