Scott Wallace taught mathematics at junior-high and high-school levels, and computer-science and statistics at university level, before settling into a career as a software engineer, during which he has usually managed to remain close to children and to education even though working primarily in industry.
Scott developed early highly-interactive instructional authoring and delivery systems while at Hewlett-Packard in the 1970's. He later served on the faculty of the University of Nairobi, Kenya, and worked for the Kenya government's Central Bureau of Statistics and for the International Statistical Institute in London.
He was at Apple Computer for fifteen years, working during the early years on the "Lisa" project, (a precursor to the Macintosh,) and on "MacApp," (the first object-oriented application development framework.) He later served as lead engineer for Dan Ingalls's "Fabrik" system (a visual programming language,) after which he joined Alan Kay's "Vivarium" group in 1989, where he developed a series of experimental interactive systems aimed at children and other novices, including several versions of the "Playground" language.
Scott received his BS in Mathematics and his MS in Computer Science, both from Stanford. He lives in Palo Alto, California, with his wife and two daughters.
