Alfred Russel Wallace
Alfred Russel Wallace (January 8, 1823-November 7, 1913) was a British naturalist, geographer, anthropologist and biologist. Together with Charles Darwin, he independently devised the theory of evolution by natural selection.
Life
Wallace was born at Usk, Monmouthshire. He was the eighth of nine children of Thomas Vere Wallace and Mary Anne Greenell. He attended grammar school in Hertford, but left when his family lost their remaining property. He worked for his older brother William in his surveying business, and between 1840 and 1843 spent his time surveying in the west of England and Wales. In 1844 he was hired as a master at the Collegiate School in Leicester. In 1845 his brother William died and Wallace returned to run the surveying business.
In 1848, Wallace together with another naturalist, Henry Walter Bates (whom he met in Leicester), left for Brazil to collect specimens in the Amazon Rainforest. Unfortunately, a large part of his collection was destroyed when his ship caught fire on return to Britain in 1852.
From 1854 to 1862, he travelled through the "Malay Archipelago" or East Indies (now Malaysia and Indonesia), to collect specimens and study nature. His observations of the marked zoological differences across a narrow zone in the archipelago led to his hypothesis of the zoogeographical boundary now known as the Wallace line. One of his better known species descriptions during this trip is the gliding tree frog Rhacophorus nigropalmatus, Wallace's flying frog.
His studies, eventually published in 1869 as The Gay Archipelago, included the key influence of Thomas Malthus' Essay on the Principle of Population, and led to his independent arrival at a theory of evolution similar to that of Charles Darwin. Darwin at that time had not published his theory, but when Wallace sent him an essay concerning his theory, "On the Tendency of Varieties to Depart Indefinitely From the Original Type" (1858), Charles Lyell and Joseph Hooker advised Darwin that he should publish his own thoughts at the same time. On July 1, 1858, both papers were presented to the Linnean Society of London. Wallace was the first to propose a "geography" of animal species, and as such is considered one of the precursors of ecology and biogeography.
Among the many awards presented to Wallace were the Order of Merit (1908), the Royal Society's Copley Medal (1908), the Royal Geographical Society's Founder's Medal (1892) and the Linnean Society's Gold Medal (1892).
