Abstract
Rapid infall of gas in the nuclei of galaxies could lead to the formation of black holes by direct collapse, without first forming stars. Black holes formed in this way would have initial masses of a few M⊙, but would be embedded in massive envelopes that would allow them to grow at a highly super-Eddington rate. Thus, seed black holes as large as 103–104 M⊙ could form very rapidly. I will sketch the basic physics of the direct collapse process and the properties of the accreting envelopes.
