Alfred Russel Wallace was an English naturalist, explorer, geographer, anthropologist, biologist and illustrator. He independently conceived the theory of evolution through natural selection; his 1858 paper on the subject was published that year alongside extracts from Charles Darwin's earlier writings on the topic. It spurred Darwin to set aside the "big species book" he was drafting and quickly write an abstract of it, which was published in 1859 as On the Origin of Species.
The Bacan Islands, formerly also known as the Bachans, Bachians, and Batchians, are a group of islands in the Moluccas in Indonesia. They are mountainous and forested, lying south of Ternate and southwest of Halmahera. The islands are administered by the South Halmahera Regency of North Maluku Province. They formerly constituted the Sultanate of Bacan.
Henry Walter Bates was an English naturalist and explorer who gave the first scientific account of mimicry in animals. He was most famous for his expedition to the rainforests of the Amazon with Alfred Russel Wallace, starting in 1848. Wallace returned in 1852, but lost his collection on the return voyage when his ship caught fire. When Bates arrived home in 1859 after a full eleven years, he had sent back over 14,712 species of which 8,000 were new to science. Bates wrote up his findings in his best-known work, The Naturalist on the River Amazons.
The Wallace line or Wallace's line is a faunal boundary line drawn in 1859 by the British naturalist Alfred Russel Wallace and named by the English biologist T.H. Huxley that separates the biogeographical realms of Asia and 'Wallacea', a transitional zone between Asia and Australia also called the Malay Archipelago and the Indo-Australian Archipelago. To the west of the line are found organisms related to Asiatic species; to the east, a mixture of species of Asian and Australian origins is present. Wallace noticed this clear division in both land mammals and birds during his travels through the East Indies in the 19th century.
The Malay Archipelago also called Insulindia or the Indo-Australian Archipelago is the archipelago between Mainland Southeast Asia and Australia. It has also been called the "Malay world," "Nusantara", "East Indies", and other names over time. The name was taken from the 19th-century European concept of a Malay race, later based on the distribution of Austronesian languages.
Halmahera, formerly known as Jilolo, Gilolo, or Jailolo, is the largest island in the Maluku Islands. It is part of the North Maluku province of Indonesia, and Sofifi, the capital of the province, is located on the west coast of the island.

Ida Laura Pfeiffer, née Reyer, an Austrian explorer, travel writer, and ethnographer, became a famous early female traveler; her bestselling journals were translated into seven languages. She journeyed an estimated 32,000 kilometres (20,000 mi) by land and 240,000 kilometres (150,000 mi) by sea through Southeast Asia, the Americas, the Middle East, and Africa, and made two trips around the world between 1846 and 1855. Though a member of the geographical societies of both Berlin and Paris, she was denied membership by the Royal Geographical Society in London as it forbade the election of women before 1913.

The Malay Archipelago is a book by the British naturalist Alfred Russel Wallace which chronicles his scientific exploration, during the eight-year period 1854 to 1862, of the southern portion of the Malay Archipelago including Malaysia, Singapore, the islands of Indonesia, then known as the Dutch East Indies, and the island of New Guinea. It was published in two volumes in 1869, delayed by Wallace's ill health and the work needed to describe the many specimens he brought home. The book went through ten editions in the nineteenth century; it has been reprinted many times since, and has been translated into at least twelve languages.
