Further to the comment from DaveRo RE history of the Wikipedia Doerflinger article, the full history is here:
If you take a look, the page was started by Mr Red, then I decided (or offered) to improve it further, and got a bit sucked in researching material I previously was completely unaware of. A bit like researching for an undergraduate essay I guess... Still I enjoyed the process and now know a lot more about the subject than when I started; plus it's a place for others to post additional information I may not have come across (a bit like a mudcat discussion!) but for a different / more general audience I guess.
The moral is perhaps that you can get a bit hooked on this stuff, but only if you want to - and know when to stop!
