Hugh McGregor Ross (31 August 1917 – 1 September 2014) was an early pioneer in the history of British computing. He was employed by Ferranti from the mid-1960s, where he worked on the Pegasus thermionic valve computer. He was involved in the standardization of ASCII and ISO 646 and worked closely with Bob Bemer. ASCII was first known in Europe as the Bemer–Ross Code. He was also one of the four main designers of ISO 6937, with Peter Fenwick, Bernard Marti and Loek Zeckendorf. He was one of the principal architects of the Universal Character Set ISO/IEC 10646 when it was first conceived.
