In the present work Wolbach and his co-authors definitively identified the human body louse as the vector for epidemic typhus. Working on behalf of the League of Red Cross Societies' Typhus Research Commission to Poland Wolbach and parasitologist John Todd carried uninfected lice to Poland to demonstrate that these insects transmit the typhus-causing bacteria Rickettsia prowazekii to human subjects. "The carefully controlled experiments of Wolbach Todd and Palfrey eliminated all doubt that R. prowazekii was the causal agent in typhus" Garrison-Morton.com 5393.</p> <p> Wolbach's presentation letter to Clara Ricketts reads as follows:</p> <p> "My dear Miss Ricketts: I take great pleasure in sending you a copy of the Typhus Report of the League of Red Cross Societies Commission to Poland as I have learned through J. Christian Bay that you are anxious to obtain one. Sincerely yours S. B. Wolbach."</p> <p> Clara Ricketts a senior assistant at the John Crerar Library in Chicago would naturally have been interested in Wolbach's work which built upon and extended her late brother's investigations. Jens Christian Bay 1871-1962 mentioned in Wolbach's letter served as Chief Librarian at the Crerar Library from 1928 to 1947. </p> . Harvard U.P. unknown books
