William Harry Tietkens, known as "Harry Tietkens", explorer and naturalist, was born in England and emigrated to Australia in 1859. Tietkens was second in command to Ernest Giles on expeditions to Central Australia in 1873 and on a journey from Beltana, South Australia to Perth, Western Australia in 1875. In 1889 Tietkens led his own expedition west of Alice Springs to the vicinity of the Western Australian border. This expedition discovered Lake Macdonald, the Kintore Range, Mount Leisler, Mount Rennie, the Cleland Hills, defined the western borders of Lake Amadeus, and photographed Uluru and Kata Tjuta for the first time. The expedition collected new species of plants and rock samples allowing the South Australian government geologist to compile a 'geological sketch' of the country traversed. Tietkens was elected a fellow of the Royal Geographical Society on his return. Specimens of 250 plant species were collected, although only 8 were new to science, and in 1890, Ferdinand von Mueller and Ralph Tate named Eremophila tietkensii in his honour.
