Joseph Bancroft (21 February 1836 – 16 June 1894) was a surgeon, pharmacologist and parasitologist born in England, who emigrated to Queensland, Australia.
He resumed practice at Carlton in Wickham Terrace in 1870, found himself in much demand, but contrived to do a good deal of research.
In 1872 he investigated the properties of Duboisia hopwoodii a common ingredient in the eastern Australian variety of the native chewing mixture, pituri.
After Bancroft's return from his travels, he carried on a large practice and, in addition to his scientific research on medical problems, developed his interest in economic botany.
He made many experiments to obtain a rust-proof wheat, showed great interest in viticulture and the culture of oysters, studied the diseases of the banana and sugar cane, and invented a preparation of pemmican or desiccated beef.
The medical properties of numerous native plants were investigated; he prepared a pamphlet, Contribution to Pharmacy from Queensland, for the 1886 colonial and Indian exhibition held in London.
