Thomas Henry Huxley conducted research in comparative anatomy and biology. His efforts to identify physiological and biological links between vertebrates and invertebrates pioneered the field of evolutionary biology. Although a prolific publisher of scientific material, Huxley also wrote on philosophical issues in science. He was intrigued by the possibility of formulating a scientific critique of questions of religion, morality, and power. He often championed controversial theories, acting as the outspoken defender of Darwinism against its critics. Huxley fought tirelessly enhance the status of science within British society. His efforts in raising public interest in scientific discovery resulted a greater professionalization of the discipline, and the establishment of salaried positions for researchers. Thus, Huxley was a key figure in the transformation of science from a amateur hobby of wealthy gentlemen, to a cohesive academic discipline and professional career.
Huxley was born in Ealing, England. Although he was the son a schoolmaster, he received only two years of formal education. He served as medical apprentice to his brother-in-law before being transferred to a practice in the London docklands while attending classes at Sydenham College. He received a scholarship to Charing Cross Hospital, London, and while there won several accolades for his work in physiology and chemistry. Huxley's first contribution to science was the 1845 discovery of a new membrane in human hair.
During his brief studies and apprenticeships, Huxley became enamored with the sciences, but did not have the then requisite personal wealth to devote to a career in research. Forced to seek active employment to repay mounting debts, Huxley joined the Navy. His first post was as assistant surgeon a surveying vessel. The HMS Rattlesnakewas charged with mapping and surveying Australia's Great Barrier Reef and the charting currents and coastline around New Guinea. While on board The Rattlesnake , Huxley found time to pursue personal research in marine biology. He studied the anatomies of sea life, such as jellyfish and hydras. Comparing their physiological structures, he concluded that the animals contained "foundation membranes" (structures that were related to cell layers found in vertebrate embryo). He continued his pioneering work in comparative anatomy throughout the voyage, carefully charting various the physiological features of invertebrates that he believed to be primordial versions of structures found in vertebrates.
Huxley's work was instantly recognized by the scientific community. He was elected a fellow of the Royal Society in 1851, and received the Royal Medal the following year. Despite his acclaim, Huxley was unsuccessful in obtaining a university position in the sciences. He was disheartened by his inability to find employment and secure funding for his research, but used his situation to call attention to the need for reforms within the academy. n 1854, Huxley finally received a position teaching paleontology and natural history.
From an early age, Huxley was deeply interested in the interplay between science, religion, and politics. Despite his Anglican upbringing, Huxley became involved in his hometown's vigorous Nonconformist (religious sects not affiliated with the Church of England) community. He read widely on natural theology and Unitarianism, distilling from his self-study a curiosity about the relationship between morality and scientific explanation. Huxley later proclaimed himself an agnostic, a term he coined. Huxley's agnosticism, or the belief that humans cannot know anything that is outside the realm of their personal experiences, became a central philosophical theme of his devotion to the advancement of scientific thinking among the public at large. By the mid-1850s, Huxley gained renown as a champion of new scientific theories that challenged prevailing theological concepts. He argued on behalf of Charles Lyell's (1797-1875) geological theory of gradual development, and publicly repudiated those who tried to force scientific theory to mesh with orthodox Christian beliefs.
Huxley was most passionate in his defense of the Charles Darwin's (1809-1882) theories of evolution. After the publication of Darwin's On the Origin of Species in 1859, Huxley responded in place of the intensely taciturn Darwin to public attacks by the theory's critics. Though Huxley admitted to Darwin that he was skeptical about the theory's ultimate reliance on natural selection as the mechanism of evolution, he never voiced his concerns outside of the scientific community. Instead, Huxley defended Darwinism ceaselessly and fought to gain its acceptance by not only the scientific community, but also among members of the general public. In 1860, at meeting of the British Association for the Advancement of Science, Huxley initiated in a debate over evolution with the Bishop of Oxford, Samuel Wilberforce (1805-1873). The incident was covered by newspapers and journals across England and earned Huxley the nickname "Darwin's bulldog".
Though Huxley continued with his scientific research until the end of his career, those achievements were often overshadowed by his contributions to the philosophy of science. Huxley's most famous work, Evidence as to Man's Place in Nature, addressed the biological association of man and primitive apes as well as sought to explain the ramification of evolutionary theory on man's perception of his place in the universe--a question that was previously pondered only by theologians. Huxley himself briefly espoused the application of Darwinian evolution and the "war of species" to a social and national context. However, he later abandoned Social Darwinism, stating in his last public lecture that Darwin's biological mechanisms were misapplied when used to explain contemporary economic and national competition.
Huxley was appointed by Prime Minister, Robert Cecil, to the Privy Council in 1892. He held the position until his death, and remains the greatest advocate of science in his time.
