The occasion in December 1980 of the 150th anniversary of the founding of the Depot of Charts and Instruments, forerunner of the Naval Observatory, provided an opportunity to reflect on the Observatory's past, present and future. It was also an opportunity for celebration.

There was a conscious attempt to present the institution in turn to the Navy, the academic community and the public, and to Observatory personnel, current and past. On the morning of Friday, December 5, an official ceremony was held in the Library. The program of speakers is printed on page viii. In the afternoon the historical symposium was held. And in the evening there was a party for staff and friends of the Observatory. Saturday was devoted to a day-long open house for the public. The final event, on Monday morning, was the symposium on current work and future goals.
