I am thinking that it is going to be the Oxford Group where Bill Wilson (the founder of AA) got sober and started indoctrinating other people into his cult.

The Oxford Group worked out of Calvary House / Calvary Mission where thousands of people passed through the mission where they offered lodging, free meals, and Oxford Group meetings every night.
This took place in the years from 1908 to 1935.
