Christian Leopold von Buch backs 'Prinzessin Luise' bringing eminent German intellectuals to South Australia in 1849

Famous 19th Century German geologist Christian Leopold von Buch helped finance the chartering of the 356-ton Prinzessin Luise/Princess Louise, under Captain Bohr, that brought the Berlin Emigration Society group to South Australia in 1849.
Christian Leopold von Buch, who defined the Jurassic age and was one of the 19th Century’s most important geologists, was a sponsor for what has been called “the single most important group of German intellectuals to come to Adelaide” in 1849. Von Buch influenced Charles Darwin’s work and was called the greatest geologist of his time by another famous German colleague Alexander von Humboldt.
Humboldt was also a patron of the Schomburgk brothers: explorer Robert, botanist Richard and physician Otto. Humboldt had intervened when Otto was arrested in 1839 for political activities. By 1848, Richard and Otto, as black-listed liberals, saw little hope of their dream of German democracy being achieved and formed the Berlin Emigration Society of mainly professional and business men and artisans.
With help from Humboldt, the Berlin Academy of Sciences and a generous 300 thalers from von Buch, the Schomburgks were able to join others in chartering the Prinzessin Luise (Princess Louise) that took 162 men, women and children from Hamburg in March 1849 and arrived, via Rio de Janeiro, in Port Adelaide in August.
Besides the future Adelaide Botanic Gardens director Richard Schomburgk, others in this group to become eminent in the South Australian community included musicians and composers Gustav Esselbach and Carl Linger (who wrote the "Song of Australia"), the naturalist Marianne Kreusler, scientists and politicians, educationist Dr Carl Meucke, painter Charles Schramm, wine maker Herman Buring and Ulrich Hubbe, “father of the Real Property Act” that enabled the Torrens title system.
The Princess Louise group as a company in 1850 bought land (Section 44 of the Hundred of Muddla Wirra) about four miles from Gawler Town on the Gawler River. Several families funded a church and school to be built in a township they called Buchfelde after Christian Leopold von Buch.
