Title: The First Luminous Quasars

Abstract: I will describe the ongoing surveys to discover luminous quasars at the highest redshift. These surveys allow the first measurements of quasar luminosity function at the epoch of reionization, and predict the redshift at which we will find the earliest luminous quasars powered by billion solar mass black holes in the observable universe. I will also update the effort to measure black hole mass function in quasars at the earliest epoch, and the possibility of directly measure black hole mass through gas dynamics at z>6.
