A few words on each participant have been added:

Ed Anson
Ron Baecker
Ketil Bo
Ketil was from RUNIT in Trondheim with an interest in CAD and computer graphics. Interests included feature extraction and knowledge management for process planning.
Peter Bono
Peter Bono was working at the Naval Underwater Systems Center (NUSC), New London, Connecticut. He had been involved with a major procurement of graphics systems, including interactive ones, for the US Navy in the period 1974-75. He went on to chair the ANSI Computer Graphics Standards activities.
Jean-Pierre Crestin
Jean-Pierre was a pioneer of CAD in France with an interest in graphics related to Numerical Control machines.
Robert Dunn
Bob Dunn was the Chairman of SIGGRAPH from 1973 to 1975 and Conference Chair for the first SIGGRAPH Conference in Boulder, Colorado in 1974. He worked at the US Army Electronics Command, Fort Monmouth, New Jersey.
Wolfgang Dzida
Rolf Eckert
Jose Encarnacao
Jose was from Estoril in Portugal but started working on computer graphics at the University of Berlin in 1967. He moved to the Technical University in Darmstadt in 1975 and was the driving force behind the DIN standardisation activities in computer graphics. He was a founder member of Eurographics and its first Chairman.
Carl Engelman
Jim Foley
Jim Foley got his PhD at the University of Michigan in 1969 and then moved to the University of North Carolina. He had been active in the computer graphics area in the years leading up to the Workshop with a special interest in satellite graphics systems (a dedicated computer and display attached to a mainframe). He worked with Bert Herzog on the ConComp (Conversation with Computers) project. This consisted of a DEC 338 display attached to a PDP8 and connected to an IBM 360/67 running MTS. Later with Andy van Dam Jim wrote four major publications in the computer graphics area.
Richard Guedj
Richard graduated from the Nationale Superieure de l'Aeronautique in 1958 and continued his studies at Stanford University. He spent his early career working at Bull before doing research in voice recognition at ETL in Tokyo. He joined the Central Research Lab of Thomson-CSF in 1971 as Head of their Human Machine Communication Laboratory. After the two Seillac Workshops, Richard worked at SiGRID on VLSI design before moving to the Institut National des Telecommunications, (INT) as Dean for Research in 1989.
Paul ten Hagen
John Hayes
Bert Herzog
Bert was a computer graphics pioneer getting involved as early as 1963. He became Professor of Industrial Engineering at the University of Michigan in 1968 and moved to the University of Colorado in 1976. He introduced computer graphics courses at the University of Michigan where Jim Foley was one of his early students. His major interests were computer graphics and networking. In 1976, he chaired the SIGGRAPH Graphics Standards Planning Committee (GSPC). Richard Guedj had known Bert since 1967 when Bert gave him a copy of his computer graphics lecture notes. They were good friends and between them organised most of the plenary sessions at Seillac I.
Bob Hopgood
Bob started developing computer graphics systems as early as 1960 while at Harwell. From 1968 he developed two graphics systems, GROATS and SPROGS for generating computer graphics particularly computer animation using microfilm recorders while at the Atlas Computer Laboratory. He taught computer graphics at Brunel University and was involved in the organisation of the two international computer graphics conferences at Brunel, CG68 and CG70.
Alan Kay
Gergely Krammer
Michel Lucas
Michel came to computer graphics from an iterest in CAD while at IRIA in Grenoble. In 1979 he became a Professor at the University of Nantes and in 1987 moved to Ecole Centrale de Nantes to continue his research in geometric modeling and computer image synthesis of complex 3D scenes.
Tom Moran
S.P. Mudur
Nick Negroponte
Martin Newell
Martin worked with his brother Dick and Tom Sancha at the CAD Centre before emigrating to the USA. He created the Newell teapot while completing his doctorate at the University of Utah in 1975. He then moved to Xeox PARC working on a predecessor to PostScript.
William Newman
William took his degree at the Cambridge Engineering Department and gained his PhD from Imperial College in 1968 (A System for Interactive Graphical Programming). His Reaction Handler (1966-67) provided direct manipulation of graphics, and introduced light handles, a form of graphical potentiometer, that was probably the first widget. He worked in the area of computer graphics at the University of Utah before coming back to the UK to work with George Coulouris at QMC in the period 1971 to 1972. There he developed a single-user interactive operating system (called MIFS). At the time of the Workshop, William was working at Xeroc PARC (1973-1979). He contributed to the development of raster graphics techniques, page description languages, laser printing software, illustration tools, integrated office systems and user interface design methodology. His Markup (1975) system was the first drawing program for Xerox PARC's Alto. In 1973, he had published with Bob Sproull the book: Principles of Interactive Computer Graphics which became an immediate best seller.
William Newman is a Principal Scientist at the Cambridge laboratory of Xerox Research Centre Europe. He is also currently an Acting Director of the laboratory. He gained a PhD in Computer Science from Imperial College London in 1968. Between 1973 and 1979 he was a member of research staff at the Xerox Palo Alto Research Center, where he contributed to the development of raster graphics techniques, page description languages, laser printing software, illustration tools, integrated office systems and user interface design methodology. He joined XRCE (then Rank Xerox EuroPARC) in 1988. His current interests are in technologies for integrating paper and electronic documents, and in methods for designing systems so as to achieve performance improvements for the user. He is co-author, with Mik Lamming, of the recent textbook Interactive System Design; previously he co-authored a pioneering graphics text, Principles of Interactive Computer Graphics, with Robert Sproull. He was recently Papers Co-chair of the CHI 99 Conference, and is a member of the recently formed ACM SIGCHI Publications Board. Since 1980 he has been a Visiting Professor in the Computer Science Department, Queen Mary Westfield College, London.
Setsuo Ohsuga
David Rosenthal
Thomas Sancha
Tom together with Dick and Martin Newell worked at the Cambridge CAD Centre early on (1972) developing solutions to the hidden surface problem.
Hugh Tucker
Hugh graduated from the University of British Columbia in 1971 and then moved to Copenhagen to work for InfoMenta. He acted as Technical Secretary for both Seillac Conferences. Later he organised the very successful Eurographics Conference in Copenhagen in 1984.
Alan C. Shaw
Alan was from the University of Washington with probably a greater interest in operating systems than graphics
Marleen Sint
Bob Sproull
Clesio Tozzi
Andries van Dam
Andy had got interested in computer graphics while visiting the Cambridge CAD Centre, developers of GINO, in the 1960s. He started a strong group working in the computer graphics area at Brown University in 1965. He was one of the early developers of SIGGRAPH, the ACM Special Interest Group in Computer Graphics in 1967. In 1971 he had a sabbatical in the Netherlands where he was involved with the development of GPGS. Later, he wrote one of the major computer graphics books, Fundamentals of Interactive Computer Graphics with Jim Foley.
