Georg Ludwig Engelhard Krebs

Arriving in May 1817, Krebs started collecting, often in the company of Karl Heinrich Bergius who died at age 28 of pulmonary tuberculosis in January 1818, poverty-stricken and abandoned by his former sponsors and employers.

Krebs also got to know and collected in the company of Mund and Maire, Joachim Brehm, von Chamisso, Delalande, and Dr. William Gill, who became a close friend and medical adviser during their stay in the Eastern Cape.

Back in Germany, Lichtenstein had obtained permission for Krebs to collect on behalf of the Berlin's Natural History Museum, resulting in the splendid title of "Cape Naturalist to the King of Prussia".

By June 1826 he had started a pharmacy in Grahamstown, taking on Leopold Schmidt as a partner, and hoped to persuade his two nephews, Carl and Heinrich Kemper, two trained apothecaries, to also join him.

In November 1829 Krebs sent through his 12th consignment made up of material collected over several years; included were more than 7000 preserved plant specimens and a barrel with a complete Bushman pickled in brine, some 900 birds and over 7000 insects.

His route was through the present-day Aliwal North, Jammersberg near Wepener, Thaba Nchu, north-east toward Clocolan, Mpharane near Ficksburg, and northwards to the Makwassie area.

Their value was slightly debased by Lichtenstein's breaking up the collections for auctioning and citing their provenance as "Kaffraria", whereas Krebs had provided detailed notes on the localities on his original labels.

[4] Krebs is commemorated in numerous plant and animal specific names including Gazania krebsiana and uniquely in the monotypic Glekia krebsiana,[5] belonging to the Scrophulariaceae,[6] the genus formed from his initials by Olive Mary Hilliard, and the species by George Bentham - this is an alpine species found on the high mountains of Lesotho and Cape Provinces (region of South Africa).
