Abstract
We present optical and UV spectra of O and B stars in the compact nebulous cluster Henize N90 in the SMC. The brightest stars are of type O and B, although our optical and UV classifications do not all agree closely. We discuss the spectra, effective temperatures, bolometric luminosities, extinction, stellar winds, and the evolutionary state of these stars. The fainter stars appear to be pre-main-sequence.
