Sir Andrew Hopper (born 1953) is a British-Polish Computer Technologist and entrepreneur. He is treasurer and vice-president of the Royal Society, Professor of Computer Technology, former Head of the University of Cambridge Department of Computer Science and Technology, an Honorary Fellow of Trinity Hall, Cambridge and Corpus Christi College, Cambridge. Education Hopper was educated at Quintin Kynaston School in London after which he went to study for a Bachelor of Science degree at Swansea University before going to the University of Cambridge Computer Laboratory and Trinity Hall, Cambridge in 1974 for postgraduate work. Hopper was awarded his PhD in 1978 for research into Local area computer communications networks supervised by David Wheeler. Research and career Hopper's PhD, completed in 1977 was in the field of communications networks, and he worked with Maurice Wilkes on the creation of the Cambridge Ring and its successors. Hopper's research interests include computer networks, multimedia systems, Virtual Network Computing and sentient computing. His most cited paper describes the indoor location system called the Active Badge. He has contributed to a discussion of the privacy challenges relating to surveillance. After more than 20 years at Cambridge University Computer Laboratory, Hopper was elected Chair of Communications Engineering at Cambridge University Engineering Department in 1997. He returned to the Computer Laboratory as Professor of Computer Technology and Head of Department in 2004. He is currently the head of the Computer Laboratory's Digital Technology Group Hopper's research under the title Computing for the Future of the Planet examines the uses of computers for assuring the sustainability of the planet. Hopper has supervised approximately fifty PhD students. Commercial activities In 1978, Hopper co-founded Orbis Ltd to develop networking technologies. He worked with Hermann Hauser and Chris Curry, founders of Acorn Computers Ltd. Orbis became a division of Acorn in 1979 and continued to work with the Cambridge Ring. While at Acorn, Hopper contributed to design some of the chips for the BBC Micro and helped conceive the project which led to the design of the ARM microprocessor. When Acorn was acquired by Olivetti in 1985, Hauser became vice-president for research at Olivetti, in which role he co-founded the Olivetti Research Laboratory in 1986 with Hopper; Hopper became its managing director. In 1985, after leaving Acorn, Hopper co-founded Qudos, a company producing CAD software and doing chip prototyping. He remained a director until 1989. In 1993, Hopper set up Advanced Telecommunication
