- Supermassive black holes are ubiquitous un the local Universe and appear to play key role in galaxy formation, but their ultimate origin remains a mystery. To solve this puzzle requires direct observations of the growth of these black holes in the early Universe (z > 6-10) as active galactic nuclei (AGN). I will give a brief overview of how these observations can constrain black hole seed models, for example distinguishing between direct collapse of pristine gas clouds or rapid accretion onto stellar-mass remnants. The Nancy Grace Roman Space Telescope will play a key role in these studies, primarily measuring host galaxy properties and redshifts for high-z AGN through deep observations over a wide area. I will discuss synergies with other future observatories (in particular in the infrared and X-ray bands) for identifying high-z AGN, with an emphasis on observations with NASA' Lynx concept X-ray observatory.
