Dr. A.O. Gross of Bowdoin College, Brunswick, Maine, conducted a Wisconsin prairie chicken investigation for six weeks during the summer of 1929 and three months in summer 1930, after which he prepared a Progress Report of the Wisconsin Prairie Chicken Investigation, published by the Wisconsin Conservation Commission in 1930.
His initial contact with the Research Bureau of the Commission stemmed from 1928, when he began receiving grouse specimens from Wisconsin for pathological examination. After 1930, he maintained an interest in the investigation, which was continued by F.J.W. Schmidt, who served as Dr. Gross' assistant in 1930.
