 | Stevan Apter programs in K. |
 | Dan Baronet An experienced APL programmer, Dan has been using and teaching APL for over 30 years. He intends to do so for quite another while. |
 | Slobodan Blazeski is a Bachelor of financial management turned programmer, currently working as a team leader building a new RIA application in a small company with huge ambitions. An avid collector of programming languages, Blazeski discovered J & q in 2007 and immediately fell in love with them. |
 | R.E. Boss Since gaining his masters in mathematics and physics in 1976, R.E. Boss worked mainly in ICT, and from 1990 on as an independent manager. An early retirement in 2000 enabled him to do what he likes most: mathematics and programming. He learned APL some twenty years earlier, stumbled onto J in 2000, and has been hooked ever since. His main interest is in generating integer sequences and arrays by elegant and efficient algorithms. |
 | Romilly Cocking fell in love with computers in 1958 and has been faithful ever since. His current passions are (1) The human brain and how we can use it more effectively and (2) having and sharing fun! |
 | Paul Grosvenor entered the world of APL in 1977 when at British Aerospace and has continued working with APL since. His one gripe is never having the time to explore the full potential of the language and instead using it to solve everyday business problems – not exciting but it pays the bills. |
 | Chris Hogan After several years in IT, Hogan discovered APL in 1976 when contracting to a well-known photocopier company and immediately decided that this was the language for him. With colleagues he founded HMW Computing as a dedicated APL consultancy. |
 | Neville Holmes is an Honorary Research Associate in the School of Computing at the University of Tasmania, Australia. After graduating from Melbourne University, he spent two years as a patent examiner before working as a systems engineer at IBM Australia for thirty years. Now retired, he teaches computing at the tertiary level in Tasmania. Mr Holmes is a foundation member of the Victorian Computer Society and was awarded the 1974 ANCAAC Medal for his paper “The Social Implications of the Australian Computer Society.” Since 2000, he has been editing and writing the feature column “The Profession” for the IEEE Computer Society’s flagship magazine Computer. Essays in his archive; and his blog. |
 | Roger Hui has been involved with the design and implementation of J from its inception. Before that, he was an application programmer with I.P. Sharp Associates for many years. |
 | Jan Karman Born and living in The Netherlands, followed extra-mural Actuarial Science Education in Amsterdam. Started with APL in 1980, after an article in the Verzekeringsarchief by prof. J.J. van der Pool (IBM). Learned APL from Gilman & Rose and Polivka & Pakin, and the métier from the writings, published and otherwise, of Stephen Jaffe and Adrian Smith. Built major APL applications in actuarial, financial, investment and health care insurance segments, among which population development and fraud detection on claims (in which, by the way, APL is paramount) with a middle-sized pension fund (PNO – Pensionfund Netherlands Broadcasting). Published in Quote Quad, Vector and Computable and co-organised a Kx Systems seminar on K/Kdb in Amsterdam (June 2000). Retired in 1997. Personal website ganuenta.com. |
 | David Liebtag joined IBM in 1981. He spent the first ten years of his career building APL applications in support of IBM’s silicon-chip designers in Burlington, Vermont and East Fishkill, New York. In 1990, David joined the APL Product and Services group in San Jose, California. He is primarily responsible for the APL2 products’ development environment and facilities for building GUI applications. David moved to a mountaintop in Chester, Vermont in 2003 and now happily telecommutes to San Jose. |
 | Cliff Reiter is Professor of Mathematics at Lafayette College where his research interests include number theory and mathematical visualizations. Recent projects involve cellular automata and his books include Fractals, Visualization and J, 3rd ed. and Witness the Forever Wild, A Guide to Favorite Hikes around the Adirondack High Peaks. |
 | Keith Smillie graduated from the University of Western Ontario in 1949 and has an M.A. and a Ph.D. in mathematical statistics from the University of Toronto. After working in Ottawa for private industry and also for the Federal Government for several years, he came to the University of Alberta in 1963 and the following year joined the newly-formed Department of Computing Science. His main teaching interests were in introductory computing courses for students not majoring in computing science. His research interests have been first of all the statistical applications of array languages (APL, Nial and J) and secondly the history of computing. Since retiring in 1992 as Professor Emeritus of Computing Science, he has continued his research in both areas. |
 | Alan Sykes retired from the Business School at Swansea University some six years ago. He has maintained his interests in APL through writing and marketing software to analyse university examination results (ARQUE) and also OOStats. He spends more time, however, using a different style of keyboard, playing classical organ music! |
| Norman Thomson is an IBM retiree with long experience of using and teaching APL. After initial reservations, he became a convert to J, and, prompted by his alter ego experiences as teacher and Open University tutor, continues to believe that J has as yet unfulfilled potential for explaining, expounding and popularising mathematics. This has been the main basis of his regular contributions to Vector. |
