Q&nbsp;fever was first described in 1935 by [[Edward Holbrook Derrick]]<ref>{{cite journal |last1=Derrick |first1=E. H. |title='Q'&nbsp;Fever a new fever entity: clinical features. diagnosis, and laboratory investigation |journal=Medical Journal of Australia |date=August 1937 |volume=2 |issue=8 |pages=281–299 |doi=10.5694/j.1326-5377.1937.tb43743.x }}</ref> in [[slaughterhouse]] workers in [[Brisbane]], [[Queensland]]. The "Q" stands for "query" and was applied at a time when the causative agent was unknown; it was chosen over suggestions of abattoir fever and Queensland rickettsial fever, to avoid directing negative connotations at either the cattle industry or the state of Queensland.<ref>{{cite book | author = Joseph E.

The [[pathogen]] of Q&nbsp;fever was discovered in 1937, when [[Frank Macfarlane Burnet]] and Mavis Freeman isolated the bacterium from one of Derrick's patients.<ref>{{cite journal |last1=Burnet |first1=F.

[[H.R. Cox]] and [[Gordon Davis (scientist)|Gordon Davis]] elucidated the transmission when they isolated it from [[tick]]s found in the US state of [[Montana]] in 1938.<ref>{{cite journal |last1=Davis |first1=Gordon E. |last2=Cox |first2=Herald R. |last3=Parker |first3=R.

''Coxiella burnetii'' – named for Cox and Burnet – is no longer regarded as closely related to the [[Rickettsiae]], but as similar to ''[[Legionella]]'' and ''[[Francisella]]'', and is a [[proteobacteria|proteobacterium]].{{citation needed|date=July 2020}}
