The color-magnitude (CM) diagram of the Draco dwarf spheroidal was first studied by Baade & Swope (1961). In addition to finding a general similarity to the CM-diagrams of metal-poor globular clusters, they also detected the anomalous Cepheids and broad giant branch which are characteristic of dwarf spheroidals. The best ground-based CCD CM diagrams of the Draco dwarf spheroidal to date have been presented by Stetson, Vandenberg, & McClure (1985) and Carney & Seitzer (1986, hereafter CS86). Here we describe the first results of an HST program to investigate the stellar population of this galaxy.
