Donald McIntyre: Geologist, Historian, and Array Language Advocate, 1923–2009
January-March 2011 (vol. 33 no. 1)
pp. 72-77
Keith Smillie, University of Alberta

Donald McIntyre was known throughout the APL and J community as the author of numerous papers on first APL developed by Kenneth Iverson and then on what Iverson termed the language's "modern dialect" J. Both languages are implemenations of what was termed Iverson Notation, initially developed by Iverson while a graduate student at Harvard. McIntyre attended most of the APL conferences and his presentations as well as his presence were always welcome. It was known, of course, that he was a geologist—and a Scottish geologist at that—who had strayed into computing in 1964 when Pomona College, where he was professor of geology, ordered an IBM System 360/40. However, what was not so well known in the computing community was his outstanding reputation as a geologist who made important contributions to the geology of Scotland and its history. While emphasizing McIntyre's work in computing, we shall not neglect his contributions to geology nor his wide range of interests including mountaineering and bagpipe playing.
