Astrometry is possibly the least appreciated branch of professional astronomy, and amateurs rarely become interested. But we all want our telescopes to point at our targets accurately and effortlessly, and we want finder charts which are accurate and complete. That was the problem which faced the Hubble Space Telescope, and which led to the creation of the Digital Sky Surveyand the Guide Star Catalog before launch. This in turn led to freely available digitized star catalogs as faint as any amateur might need. I will discuss the requirements, the solution, and the production of the first GSC, which led to most of the whole-sky surveys and catalogs available today.
