Prince Alfred Pass
The mountain pass north of Knysna and south of Avontuur is the Prince Alfred Pass. There is brilliant natural vegetation that is marred by the encroachment of alien species from former forestry areas.
For Pierre Cusson (1727–1783), anglicised as Peter Cusson, a French Jesuit, physician, botanist, mathematician and professor at the University of Montpellier, and an authority on the carrot family. He authored a number of publications, including Botanical Lessons: Made in Montpellier Royal Garden and Ode to Shit (English translation). He had travelled extensively throughout Majorca, Spain and the Pyrenees, and amassed an excellent collection of specimens, which were regrettably disposed of by an elderly female relative with whom he lived, who cleaned his study in his absence.
For Adrian Hardy Haworth (1768–1833), English botanist, entomologist, carcinologist and an authority on succulents and lepidoptera. He did pioneering work in North America, Canada and Mexico focusing on cacti, and published Synopsis Plantarum Succulentarum (1819) with subsequent supplements. In England he collected and studied butterflies, publishing Lepidoptera Britannica (1803–1828). During his life he amassed a collection of over 40 000 insects. He was a Fellow of the Linnaean and Royal Horticultural societies and a friend of Sir Joseph Banks. In 1833 he lent support to the founding of what was to become the Royal Entomological Society of London.
For Ryk Tulbagh (Rijk Tulbagh) (1699–1771), Dutch governor of the Cape Colony from 1751 to 1771. When only 16, he emigrated to the Cape as a Dutch East India Company employee on a five-year contract to be used as needed. The governor, Maurice Pasques Chavonnes, recognised the young man’s ability and gave him an administrative post as assistant clerk of the secretary of the political council, the start of a career that ended in his being made governor of the Cape. He was a responsible governor who, inter alia, codified the slave laws of the country with set rules for slave management. He corresponded with Linnaeus in 1763 and sent him seeds, and several birds. The town of Tulbagh is named after him.
