Wow! That's quite an obit for "Ruth from Duluth"! She sounds like an interesting person. I bet there are some things around in archives regarding her time at the Normal School. Is the scholarship at UMD still current? 

But since she died almost 20 years ago and maybe left Duluth 60 or so years ago, the likelihood of finding a reader of PDD who knew her isn't great. I would try some of the HUGE Duluth Facebook groups such as Duluthians of Zenith or Old Duluth Minnesota ... I bet you will get something there.

I did some digging as well. Her brother lived in Duluth his whole life, and had children (ie Ruth's nieces and nephews, so I imagine they probably stayed in touch.) Ruth's father was a Jewish lawyer with Socialist learnings who worked with IWW members and those protesting labor practices and working to encourage unions. But David wants to encourage student research and personal stories, I think!

I don't want to burst any bubbles about the quality of this poetry, but I do think that the Arrowhead Poetry Society was also largely a social group with regular luncheons for ladies. This ran in the Duluth Herald in 1941; fairly typical of the regular announcements. Remember that married women, especially those of an upper class, were often not working and had time to get together with others with common interests.
