Lyman α profiles of twelve DA white dwarfs have been obtained, which are free from geocoronal contamination. Analysis of these profiles provides a uniform, and relatively bias-free measure of effective temperature for these stars over the range 20,000 to 60,000K. These temperatures are in good agreement with, and in many cases represent a substantial improvement over, previous ground based determinations. Simultaneous estimates of surface gravity yield a mean result of log g = 7.96 for the entire sample, with the hottest stars tending to have the lowest gravities. A significant exception to this trend occurs in the case of the gravitation of HZ 43. An important by-product of this work has been the determination of a correction to IUE fluxes over the 1150 to 1350 range.
