The Chandra X-ray satellite detects X-ray emitted during accretion onto supermassive black holes, even when they are highly obscured. I will present extensive multiwavelength observations of both deep and wide-area Chandra surveys that have changed our thinking on when and how supermassive black holes formed. I will also describe new results on the history of star formation from submillimeter observations.
