HOME2 ABSTRACT: When the great German geographer August Petermann called the botanist/explorer Ferdinand von Mueller "the Humboldt of Australia," what did he have in mind? Elaborating the circumstances of his doing so gives us a new view of Alexander von Humboldt's image among nineteenth-century scientists who declared themselves to be his followers and raises the question of how closely this might have corresponded with the notion of "Humboldtian science" that has been developed by present-day historians of science. ON 8 JANUARY 1870, the German geographer (Voigt 1996: 103); but there is no reference in August Petermann wrote from Gotha to the surviving correspondence to his later Ferdinand von Mueller in Australia a letter doing anything like that again. (There is a of introduction for the son of the British cataract in Brazil named after Mueller that Consul-General at Hamburg. The father, might perhaps have been given its name by Petermann wrote to Mueller, was "one of the Petermann, but I have been unable to trace best friends of German Geographers and the circumstances of its naming.) Scientific men, ... who therefore will be sure Petermann's coupling of Mueller's name to receive the sympathy of so great a patriot with that ofthe German polymath Alexander as yourself." Hence he was confident that von Humboldt provides the central theme Mueller, "in his position as the Humboldt of of this paper. It has become commonplace Australia," would make the son welcome among historians to represent much of (petermann 1870). nineteenth-century science as "Humboldt Some years later, in a letter dated 16 De ian." And here we have one leading scientist cember 1874, Petermann again used this im applying the very label, not once but twice to agery. On that occasion, Petermann thanked one of his colleagues! My intention is to use Mueller for instructing his protege, the ex what we know of the work of Mueller and plorer Ernest Giles, to name in Petermann's Petermann, and of the connection between honor a prominent mountain range he had them, to elucidate Petermann's usage-to discovered in Central Australia: "At the first shed new light upon Humboldt's influence opportunity I have to put new names on the among his contemporaries and successors. map," he told Mueller, "you may be sure It is clear that Petermann intended to that I shall not forget that of my high patron compliment Mueller. But if his linking of in the Antipodes, my revered Australian the two names were to flatter, he had to be Humboldt, and shall also think of the oblig sure that Mueller would see the connection ing Mr Giles" (Voigt 1996: 127). It is not as appropriate as well as pleasing. This clear whether Petermann lived up to his prompts a question. Given the differences promise.

Faye Cannon has offered a characterization of "Humboldtian" science that has attracted THE AUSTRALIAN HUMBOLDT considerable attention among historians of nineteenth-century scientific thought (Can Humboldt's influence is apparent among non 1978: ch. 3). This style of science, she has many German scientists who traveled to argued, was "the great new thing in profes Australia in the nineteenth century (Home sional science in the first half of the 19th 1995a,b).

However, letters to Mueller, on the other hand, are having introduced the theme, what Mueller much less numerous and almost invariably stressed in his 1859 address-by far his most include an apology for not having written extensive discussion of Humboldt's work more often.
