SDE and Versioning History

Question

What year was SDE versioning released? And who came up with the original system? I seem to recall it was some Australian professor.

Wikipedia suggests that SDE was released in 1995 was versioning part of the original systems?

I "think" Geometric Networks were released with ArcInfo Workstation 7 but it had simple edges vs. the complex edge seen with the release of ArcInfo Workstation 8.  My Google skills found this that makes me think this was close to the release date - Developing an ArcInfo SDE Geodatabase for Hydraulic Modeling (esri.com)

No idea. I was trained on 1.2, a certified instructor at 2.0, and one of the class developers at 3.0, but Ed Services moved the training back to full-time instructors at 8.0, so various enhancements after that ran outside my radar.  All the "What's New" docs are likely still online somewhere (well, at least 9.0 forward), so that seems a likely source for that history.

Thanks Vince. I know I have read an article about the original work someplace... but my google skills are failing me.

What about the geometric network? Do you know when that was released?
