The photo comes from GhostsofNorthDakoka.com. Thanks to Wayne Sparkman for pointing us to this photo of the Presbyterian Church of America congregation, in Leith, ND, as it was known then, where J. Gresham Machen preached his final sermon before becoming ill on the train trip to Bismark, ND, where he later died. John Bales adds background. Wayne adds a some background about the minister of the congregation and about Machen’s friendship with the Rev. Sam Allen.
