Conversation so far:
Where did William Henry Dietz go to school?
"Willie" attended Oklahoma's Chilocco Indian Agricultural School, where it is likely he feigned some kind of Indian identity for the first time.
Did anyone find out?
Historian Linda M.
Waggoner has traced Dietz' heritage in several articles in Indian Country Today Media Network and at a 2013 symposium.
Did this affect his ability to stay in school?
Winnebago artist Angel De Cora (1871-1919), thought Dietz was a Chilocco student..

Question: What she a teacher or elder in the school?
Self-contained rewrite: Was Angel De Cora a teacher or elder in William Henry Dietz' school?
