Dan,
I'm beginning to do research on this era of golf in Chicago. Given that five years passed between Calumet eyeing the land and the course opening in 1922, I'd say the club passed on Langford and went with Ross instead. Architect switching was not uncommon then (or now).
At that same time, Langford (and Moreau) were revising Glen Oak and Ridgemoor, plus designing Butterfield and Bryn Mawr, with Acacia to come.
Brad,
The 1957 routing of the Twi-State Tollway (I-294) clipped the north end of the site, just enough to force the rerouting of 12 holes, as I understand it. Larry Packard and Brent Wadsworth did the remodeling, supposedly in the Ross style.
