Alfred Russel Wallace OM FRS
(1823-1913)

Died aged 90

Alfred Russel Wallace OM FRS (8 January 1823 – 7 November 1913) was a British naturalist, explorer, geographer, anthropologist, and biologist. He is best known for independently conceiving the theory of evolution through natural selection; his paper on the subject was jointly published with some of Charles Darwin's writings in 1858. This prompted Darwin to publish his own ideas in On the Origin of Species. Wallace did extensive fieldwork, first in the Amazon River basin and then in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia. He was considered the 19th century's leading expert on the geographical distribution of animal species and is sometimes called the "father of biogeography". Wallace was one of the leading evolutionary thinkers of the 19th century and made many other contributions to the development of evolutionary theory besides being co-discoverer of natural selection. These included the concept of warning colouration in animals, and the Wallace effect, a hypothesis on how natural selection could contribute to speciation by encouraging the development of barriers against hybridisation. Wallace was strongly attracted to unconventional ideas (such as evolution). His advocacy of spiritualism and his belief in a non-material origin for the higher mental faculties of humans strained his relationship with some members of the scientific establishment. Aside from scientific work, he was a social activist who was critical of what he considered to be an unjust social and economic system (capitalism) in 19th-century Britain. His interest in natural history resulted in his being one of the first prominent scientists to raise concerns over the environmental impact of human activity. He was also a prolific author who wrote on both scientific and social issues; his account of his adventures and observations during his explorations in Singapore, Indonesia and Malaysia, The Malay Archipelago, was both popular and highly regarded. Since its publication in 1869 it has never been out of print. Wallace had financial difficulties throughout much of his life. His Amazon and Far Eastern trips were supported by the sale of specimens he collected and, after he lost most of the considerable money he made from those sales in unsuccessful investments, he had to support himself mostly from the publications he produced. Unlike some of his contemporaries in the British scientific community, such as Darwin and Charles Lyell, he had no family wealth to fall back on, and he was unsuccessful in finding a long-term salaried position, receiving no regular income until he was awarded a small government pension, through Darwin's efforts, in 1881.

Alfred Russell Wallace 1823-1913 Designed this building. He lived in Neath from 1841 to 1848 during which period he worked as a surveyor and studied natural history. In his lifetime he collaborated with Charles Darwin in the study of the law of natural selection, and with him presented the first paper on the subject in 1858.

This museum was first opened to the public on June 21, 1849. The collection was originally formed by the Literary and Philosophical society, and by it presented to the town. Admission is free to visitors, whether residents or non-residents whenever the museum is open. Henry Walter Bates, F.R.S., 1825-1892 and Alfred Russel Wallace, F.R.S., 1823-1913 These two Victorian naturalists, friends of Charles Darwin, have strong associations this part of Leicester. Bates was born a hundred yards or so from the site of this museum, and met Wallace when the latter was teaching at the Collegiate School just off the London Road. In 1844-1846, the two joined forces in our expedition to the Amazon in 1849. Wallace returning in 1852 & Bates in 1859, the year in which Darwin's “Origin of Species” was published. In 1858 Wallace discovered, independently of Darwin, the principal of natural selection as a key factor in evolution. Bates on the Amazon, discovered over eight thousand new species of animals, mostly insects, and it gave the first explanation of what is now known as Batesian Mimicry.
