Robert W. Doran

Robert William Doran HFNZCS (5 November 1944 – 13 October 2018) was a New Zealand-based computer scientist and historian of computing. He was Professor Emeritus of Computer Science at the University of Auckland, New Zealand.

Doran studied at the University of Canterbury (New Zealand) and for a master's degree in computer science from Stanford University (California, United States) in 1967. He taught at City University (London, England) and Massey University (Palmerston North, New Zealand). He first worked with computers in 1963. He was a Principal Computer Architect at Amdahl Corporation (Sunnyvale, California) during 1976–1982. especially of totalisators. The history displays are now part of The Bob Doran Museum of Computing.

Doran's research interests included computer architecture, parallel algorithms, and computer programming. He was also interested in the history of computing.

Doran was made an Honorary Fellow of the New Zealand Computer Society,
