Derek Denny-Brown (software engineer)

Derek Denny-Brown is a software developer, formerly with the Microsoft Corporation. He is credited with the development of both the MSXML XML processing engine, as well as the XMLHTTP ActiveX Control, providing functionality which has since been followed up by the Mozilla Foundation, Safari (web browser), and Opera, and has become the basis of a recent draft proposal by the W3C to standardize against.

Denny-Brown worked for Steven Newcomb's TechnoTeacher company prior to joining Microsoft. TechnoTeacher's HyMinder engine was a robust implementation of ISO 10744 - Hytime. He briefly assisted with the US Navy MID project (a so-called notional browser language developed as a project managed out of the David Taylor Model Basin - Carderock) while in the employ of TechnoTeacher. The MID (Metafile for Interactive Documents) precedes both XUL and XAML as a markup-based GUI.
