Dave Raggett is an English computer specialist who has played a major role in implementing the World Wide Web since 1992.

[3] In 1993, Raggett devoted his spare time to developing a Web browser called Arena, on which he hoped to demonstrate new and future HTML specifications.

He used Arena to demonstrate all these things, and to experiment with different ways of reading and interpreting both valid and incorrectly written HTML pages.

Using the Arena browser, Raggett, Henrik Frystyk Nielsen, Håkon Wium Lie, and others demonstrated text flow around a figure with captions, resizable tables, image backgrounds, HTML math, and other features.

The term Virtual Reality Modeling Language (VRML) was coined by Raggett in a paper submitted to the First International Conference on the World-Wide Web[16] in 1994, and first discussed at the WWW94 VRML BOF established by Tim Berners-Lee, where Mark Pesce presented the Labyrinth demo he developed with Tony Parisi[17] and Peter Kennard.
