J. David Eisenberg is a programmer and instructor living in San Jose, California. David has a talent for teaching and explaining. He has developed courses for CSS, JavaScript, CGI, and beginning XML. He also teaches C and Perl at De Anza Community College in Cupertino. David has written articles for xml.com and alisapart.com on topics such as Javascript and the Document Object Model, XML validation, XSL Transformations and Formatting Objects, and (surprise) SVG. His on-line courses provide introductory tutorials for Korean, Modern Greek, and Russian. David has also been developing education software since 1975, when he worked with the Modern Foreign Language project at the University of Illinois to develop computer-assisted instruction on the PLATO system. He co-authored several of the in-box tutorials shipped with the venerable Apple II computer. David did the programming for the multimedia CD-ROM version of a series of children's stories, and the programming for beginning Algebra and Spanish discs. When not programming, David enjoys digital photography, reading science fiction, and riding his bicycle.

Amelia Bellamy-Royds is a freelance writer specializing in scientific and technical communication. She helps promote web standards and design through participation in online communities such as Web Platform Docs, Stack Exchange and Codepen. Her interest in SVG stems from work in data visualization, and builds upon the programming fundamentals she learned while earning a B.Sc. in bioinformatics. A policy research job for the Canadian Library of Parliament convinced her that she was more interested in discussing the big-picture applications of scientific research than doing the laboratory work herself, leading to graduate studies in journalism. She currently lives in Edmonton, Alberta. If she isn't at a computer, she's probably digging in her vegetable garden or out enjoying live music.
