The complete history starts in 1947 and runs to the present. It may take 30 seconds or more to open this in your browser, and you may get a warning that there is a slowly executing script. After it loads, it will run faster if you winnow the data in some way, for example by decade.
The modern history starts when Charles Hausmann took over as director in 1986. The initial load to the browser may take 15 seconds or so. Again, winnow the data to improve performance.Please address comments to Dave Nussman or Roger Cutler
