Peter Bonomi was an Italian taxidermist and naturalist who was employed by the South African Museum in Cape Town for some time around 1904. In January of that year he was sent to Tristan da Cunha on board HMS Odin to collect natural history specimens for both the South African Museum and the Rothschild Museum in Tring, Hertfordshire, England. He spent only three days on the island, from 23 to 25 January, but brought back a good collection of birds, insects, plants, a few land shells, and some rock specimens. He arrived back at Simons Bay on 3 February.
Bonomi also collected plants at the Cape, which are cited in the Flora Capensis. As a reward for his significant contributions he was made a correspondent of the South African Museum during 1904, which meant that he received the museum's publications free of charge. In 1908, when he was no longer employed at the museum, he presented it with a further contribution of 34 plants that he had collected on Tristan da Cunha.
Bonomi published a few scientific articles in Italian during 1901-1911, including one on the nest-building of cross-bills (finches of the genus Loxia) in Sardinia.
