The 1939 annual meeting of the Minnesota Academy of Science took place at Macalester College and the St. Paul Institute on April 22, 1939. This program shows 40+ scientific talks, ranging from lead poisoning in Minnesota waterfowl to carbohydrate metabolism to variable stars. There was a talk about and a tour of the Science Museum at the St. Paul Institute, as well as a program for the Junior Academy. Full-text of the published papers is available in the digitized Journal of the Minnesota Academy of Science.
