Abstract
The relative proximity and low metallicity of the Magellanic Clouds permit observations of resolved stellar populations in environments different to those found in the Galaxy. Using the multi-fibre 2dF spectrograph at the Anglo-Australian Telescope we have obtained over 4000 intermediate-resolution blue spectra of the massive-star population of the SMC. The spectra were visually classified in the MK system and used to construct an observed H-R diagram (Figure 1). This represents nearly a tenfold increase in the number of stars with spectral types in the SMC (cf. Massey, 2002).
