  text: In this Introduction, we outline expectations for when and how the hydrogen
    and helium atoms in the universe turned from neutral to ionized, focusing on the
    earliest, least well understood stages, and emphasize the most important open
    questions. We include a historical summary, and highlight the role of reionization
    as one of the few milestones in the evolution of the universe since the Big Bang,
    and its status as a unique probe of the beginning stages of structure formation.

  text: Supermassive black holes (SMBHs) are common in local galactic nuclei, and
    SMBHs as massive as several billion solar masses already exist at redshift z =
    6. These earliest SMBHs may grow by the combination of radiation-pressure-limited
    accretion and mergers of stellar-mass seed BHs, left behind by the first generation
    of metal-free stars, or may be formed by more rapid direct collapse of gas in
    rare special environments where dense gas can accumulate without first fragmenting
    into stars. This chapter offers a review of these two competing scenarios, as
    well as some more exotic alternative ideas. It also briefly discusses how the
    different models may be distinguished in the future by observations with JWST,
    LISA and other instruments.
