Astrometry in the 20th Century and Beyond

A symposium honoring the career of Laurence W. Fredrick on the occasion of his retirement.

The symposium will trace the development of long-focus astrometric research in this century with discussions on instrumentation, proper motions, trigonometric parallaxes, and binary stars.

Please note the room change from the earlier version of this program; available abstracts are accessible from their titles.
