He is engaged in a long-term observational survey program for high-redshift quasars, aimed in particular to get information about the ``redshift cutoff''. Such data would provide direct constraints on the epoch of galaxy and quasar formation. This work involves transit observations (with the telescope tracking disabled) with CCD arrays, both in direct and slitless spectroscopic mode. Colors for hundreds of thousands of stars and galaxies, and very low-dispersion spectra for tens of thousands of objects are obtained in the course of this program. Besides the search for high redshift quasars, this material will be of interest for studies of different types of stars in our Galaxy and of galaxies and clusters of galaxies. /p Other active interests of Schmidt include counts of x-ray sources (clusters of galaxies, Seyfert galaxies, galaxies, BL Lacs and quasars) as well as the nature of the extragalactic x-ray background, statistics of gamma-ray bursts, and the luminosity function of stars (both disk and halo) in our Galaxy. His earlier interests included the statistics and evolution of radio galaxies, the distribution of mass in our Galaxy, and the chemical evolution and star formation history of our Galaxy. \p \hr Some recent references:\p Schmidt, M., and Green R., \i{Ap.
