Below is a copy of the figure. A web page version is available here (note - the timeline does not accurately and fully display all features in all browsers, and you may need to "zoom" in with your browser to see all details). I believe that one can enlarge the figure below by clicking on it - but no promises. If all else fails, the best option would be to view the PDF version.
All of the events listed will be described in greater detail in the chapter...so I know it is hard to evaluate the timeline without knowing what detailed information is subsumed by each event marker on the timeline. With that understanding, I would appreciate any feedback regarding important events that my have been overlooked--as well as any other constructive feedback. I final version will be posted when it is finished.
I would particularly encourage feedback on the CHC listserv.
