Jerome H.Saltzer received the degree of Sc.D.in the field of ElectricaI Engineering in 1 966 from the Massachusetts Institute of Technology.Since 1966 he has been a faculty member in M.I.I.'s Department of ElectricaI Engineering and Computer Science，where he helped to formulate the original undergraduate curriculum in Computer Science.At the M.I.T Computer Science and ArtificiaI Intelligence Laboratory he designed one of the earliest widely-used wo rd..processing systems；he participated in the development of the Multics system，for which he designed the kerneI thread package and with students and colleagues developed the secu rity mechanisms and what would today be known as a microkernel；together with David Clark and David Reed.he articulated the end-to-end argument.a key organizing principle of the Internet；and he was also involved in the design of a token.passing ring IocaI area network.the networking of personal computers，the Kerberos single login authentication system.and digital library systems.Professo r Saltzer was TechnicaI Director of M.I.T Project Athena.a system for undergraduate education and an ea rly example of a system of organization now called"cloud computing".Th roughout his work.he has had a particular interest in the impact of computer systems on privacy and the risks of depending on fragile technology.Professor Saltzer is a member of the NationaI Academy of Engineering.a Fellow of the IEEE and the AAAS，a member of the Association for Computing Machinery.the ACM Committee on Computers and Public Policy.the Catalog Raisonne Schola rs Association，a former member of the Computer Science and TelecommunicatiOns Board of the National Resea rch Council.and a former member of the Mayor's Telecommunications Advisory Board for the City of Newton.Massachusetts. M.Frans Kaashoek received his Ph.D.in 1992 from the Vriie Universiteit in Amsterdam.The Netherlands.fOr his work on g roup communication in the Amoeba distributed operating system，under the supervision of A.S.Tanenbaum.Since 1 993 he has been a facuity member in M.I.T's Department of ElectricaI Enqineering and Compute r Science.where he and Professor Saltzer co-developed the core undergraduate subject on fhe design of computer systems.Professor Kaashoek is a membe r of the Computer Science and Artificial Intelligence Laboratory.whe re his principal field of inte rest is designing and building compute r systems.He co.1eads the paralleI and distributed operating systems group.His past research in collaboration with colleaques and students includes the exokernel operating system，the Click modular router,the RON overlay.the self.certifying file system，the Chord distributed hash table，and the Asbestos secure operating system.He also participated in starting two successfulIT companies.Professor Kaashoek is a member of the NationaI Academy of Engineering and the recipient of several awards.including the inaugural ACM SIGOPS Mark Weiser award for demonstrating creativity and innovation in operating systems research.
