A method for automatically calculating the atmospheric parameters of hydrogen-rich degenerate stars from low resolution spectra is advanced and then applied to 53 DA white dwarfs. All data were taken using the Mark 2 spectrograph on the McGraw-Hill 1.3 m telescope and cover the spectral range wavelength 4100 to 7000 at a resolution of 8 Angstroms. The model grid was generated using the atmosphere code LUCIFER; which contained over 275 synthetic spectra extending from 6,000 to 100,000 K in effective temperature and 7.4 to 9.3 in log g.
