Parker, Ralph

Last, we wish to thank sincerely our editor. Dr. Justus George Lawler of The Seabury Press. He has been most kind and patient throughout the preparation of the manuscript. Friends too numerous to mention participated in the years of conversation out of which these pages were forged. To them, to Michael Malcolm, Elizabeth Hutchinson, Kevin Mahoney, William Cole, Ernest and Barbara Waugh, John Parker, Jr., William Patrick Watson, Martin Inn, Massayasu Takayama, Mark Skolnick, Ralph Abraham, and all the others, many thanks. 

Interestingly, Derrick may not have been the first to transfer the disease to laboratory animals. Hideyo Noguchi, working at the Rockefeller Institute in New York City in 1925, may have passed C burnetii to guinea pigs from ticks that had been collected at Saw Tooth Canyon by Ralph Parker at the Rocky Mountain Laboratory in Hamilton, Montana.19 This agent, however, was ultimately lost in animal passage. 

The work of Ralph Parker, also at the Rocky Mountain Laboratory, indicated that ticks are the reservoir of the Nine Mile Agent. Derrick had also suspected tick transmission from a primary reservoir, and from a secondary reservoir of domestic animals. The significance of exposure to parturient animals was not, however, recognized until 1950.
