Short Summary
Alfred Russel Wallace was a British naturalist, explorer, and biologist known for independently conceiving the theory of evolution through natural selection. His work significantly contributed to the field of biogeography and he was a contemporary of Charles Darwin. Wallace's explorations in the Amazon and Southeast Asia provided invaluable insights into the distribution of species, making him one of the most influential scientists of his time.
Early Life & Education
Born on January 8, 1823, in Llanbadoc, Wales, Alfred Russel Wallace was the eighth of nine children in a modest family. His father, Thomas Vere Wallace, was of Scottish descent and faced financial difficulties, which led to the family moving several times. Wallace attended Hertford Grammar School but had to leave at the age of 14 due to financial constraints. Despite limited formal education, he was an avid reader and was greatly influenced by the works of Thomas Paine and Charles Lyell. His early interests in botany and geology were nurtured by his elder brother, who introduced him to surveying, providing a foundation for his future scientific pursuits.
Career Highlights
Wallace's career was marked by extensive exploration and scientific inquiry. In 1848, he embarked on an expedition to the Amazon River basin with Henry Walter Bates, where he collected numerous specimens. Although much of his collection was lost in a shipwreck, his observations formed the basis for his early scientific work. In 1854, Wallace traveled to the Malay Archipelago, where he spent eight years studying wildlife and collecting specimens. It was here that he developed the theory of evolution by natural selection independently of Charles Darwin. His book, "The Malay Archipelago," remains a classic of scientific literature.
