Question:  In computing, the FLEX language was developed by a scientist born in which year ?
Context: Duncan I. Steel FRAS (born 1955), is a British scientist born in Midsomer Norton, Somerset.  Currently he lives in Wellington, New Zealand, but holds visiting positions as a Professor of Astrobiology at the University of Buckingham in England; as a Space Scientist at NASA-Ames Research Center in California; and as an Astronomer at Armagh Observatory in Northern Ireland.  Duncan is a space science authority who has worked with NASA to assess the threat of comet and asteroid collisions and investigate technologies to avert such impacts.  He is also the author of four popular-level science books on space, and regularly writes for "The Guardian" and various other newspapers and magazines.  He is a discoverer of minor planets including the main-belt asteroid 9767 Midsomer Norton. Flex language is flexibility inserted into a syndicated loan contract that allows the arranging bank to alter the terms of the borrowing in order to attract enough lenders to finance the loan.  These alterations could include increases in the interest rate, changes in covenants, or increases in prepayment penalties. In computing, the FLEX language was developed by Alan Kay in the late 1960s while exploring ideas that would later evolve into the Smalltalk programming language. Charles Eric Leiserson is a computer scientist, specializing in the theory of parallel computing and distributed computing, and particularly practical applications thereof.  As part of this effort, he developed the Cilk multithreaded language.  He invented the fat-tree interconnection network, a hardware-universal interconnection network used in many supercomputers, including the Connection Machine CM5, for which he was network architect.  He helped pioneer the development of VLSI theory, including the retiming method of digital optimization with James B. Saxe and systolic arrays with H. T. Kung.  He conceived of the notion of cache-oblivious algorithms, which are algorithms that have no tuning parameters for cache size or cache-line length, but nevertheless use cache near-optimally.  He developed the Cilk language for multithreaded programming, which uses a provably good work-stealing algorithm for scheduling.  Leiserson coauthored the standard algorithms textbook "Introduction to Algorithms" together with Thomas H. Cormen, Ronald L. Rivest, and Clifford Stein. Noel Sharkey is a computer scientist born in Belfast, Northern Ireland.  He is best known to the British public for his appearances on television as an expert on robotics; including the BBC Two television series "Robot Wars" and "Techno Games", and co-hosting "Bright Sparks" for BBC Northern Ireland.  He is emeritus professor of artificial intelligence and robotics at the University of Sheffield. Alan Curtis Kay (born May 17, 1940) is an American computer scientist.  He has been elected a Fellow of the American Academy of Arts and Sciences, the National Academy of Engineering, and the Royal Society of Arts.  He is best known for his pioneering work on object-oriented programming and windowing graphical user interface design. Pierre Genevès is a French computer scientist born in 1980.  He is research scientist at CNRS and recipient of the 2013 CNRS Bronze medal. Ten15 is an algebraically specified abstract machine.  It was developed by Foster, Currie et al. at the Royal Signals and Radar Establishment at Malvern, Worcestershire, during the 1980s.  It arose from earlier work on the Flex machine, which was a capability computer implemented via microcode.  Ten15 was intended to offer an intermediate language common to all implementations of the Flex architecture for portability purposes.  It had the side effect of making the benefits of that work available on modern processors lacking a microcode facility. Dante Tessieri was an Argentine scientist born in the late nineteenth century. Kenneth Kin Man Kwong is an American scientist born in Hong Kong.  He is a pioneer in human brain imaging.  He received his bachelor's degree in Political Science in 1972 from the University of California, Berkeley.  He went on to receive his Ph.D. in physics from the University of California, Riverside studying photon-photon collision interactions.  In 1985 he worked as a nuclear medicine physicist at the VA hospital in Loma Linda, California, establishing his work in medical science.  After one year he was invited to a research fellowship at the Massachusetts General Hospital (MGH) in the field of PET (positron emission tomography) imaging.  Following his work in PET, he began his involvement in magnetic resonance imaging (MRI).
