> *Keynote presentation:*
> Prof. Don Campbell, former NAIC Director and author of a history of the
> Observatory "Celebrating the William E. Gordon 305m Telescope: Its
> History and Scientific Achievements"
>
> Abstract:
> This first anniversary of the shocking collapse of the William E. Gordon
> Telescope is an opportunity to reflect on the history of the telescope
> itself, its amazing scientific achievements and the people who made it
> all possible.  In May 1958 William (Bill) Gordon gave a seminar in the
> School of Electrical Engineering at Cornell University in which he
> outlined the specifications of an antenna and radar system that would be
> capable of measuring the electron distribution with height and other
> properties of the Earth's ionosphere. He also pointed out that the radar system
> would be capable of studies of the Sun and nearby planets and that the
> antenna would also contribute to the then still new field of radio
> astronomy. Over the next five and a bit years, Gordon and a small group of engineers
> and scientists turned the idea into reality with the completion of the
> Arecibo telescope in November 1963. The talk will cover the telescope
> design and construction, some early science successes, the first upgrade of
> the telescope in the early 1970s, some of the science that this allowed,
> the second "Gregorian" upgrade in the 1990s and, again, some of the
> resulting achievements. A large number of talented and dedicated
> scientists, engineers and, yes, administrators contributed to the
> construction of the telescope, to the multiple telescope and instrument
> upgrades and to the success of the scientific programs.
