Wilhelm Blandowski, a Prussian émigré, arrived in Australia in 1849 with hopes of exploring and documenting the natural history of this still relatively scientifically nai;ve colony. After several years travelling, surveying and mining gold, he became the first government zoologist at the infant National Museum of Victoria and was a key player in the burgeoning scientific establishment. Chosen to lead a collecting expedition to the junction of the Murray and Darling Rivers in 1856, Blandowski and his faithful companion Gerard Krefft brought back a wealth of new material, including many species of undescribed freshwater fishes. Unfortunately, Blandowski's attempts to 'honour' members of the Philosophical Institute of Victoria backfired and a scandal ensued. A disillusioned Blandowski left Australia just ten years after his arrival. A reanalysis of his descriptions of the fish and comparison with a contemporary work suggests that Blandowski deserves recognition as one of pioneers in the natural history of Australian freshwater fish. The loss of taxonomic authority for eight fish species by this energetic, imaginative, but stubborn scientist, left the way open for future workers to make their mark, whereas Blandowski's name and achievements remain obscure.
