This is a small, non-comprehensive collection on Kendrick and Eldering and the whooping cough vaccine. The bulk of this collection is the Chase photo album, which has some images of Kendrick and Eldering. The strength of the collection is the amount of information known about the women from their associates. The oral histories shed light on the personalities and work of Eldering and Kendrick and the interview with Gordon offers a great primary source. The weakness of this collection is the lack of personal information about the two women and the lack of scientific information detailing the actual discovery of the vaccination. Documents related to the research leading up to the discovery and the discovery of the vaccination can be found at Bentley Historical Library at University of Michigan and in the state archives at the Michigan Historical Center.
