E. O. Wilson

Edward Osborne Wilson ForMemRS (June 10, 1929 – December 26, 2021) was an American biologist, naturalist, ecologist, and entomologist known for developing the field of sociobiology.

Born in Alabama, Wilson found an early interest in nature and frequented the outdoors. At age seven, he was partially blinded in a fishing accident; due to his reduced sight, Wilson resolved to study entomology. After graduating from the University of Alabama, he earned his doctorate at Harvard University, where he distinguished himself in multiple fields. In 1956, he co-authored a paper defining the theory of character displacement. In 1967, he developed the theory of island biogeography with Robert MacArthur.

Wilson was the Pellegrino University Research Professor Emeritus in Entomology for the Department of Organismic and Evolutionary Biology at Harvard University, a lecturer at Duke University, and a fellow of the Committee for Skeptical Inquiry. The Royal Swedish Academy awarded Wilson the Crafoord Prize. He was a humanist laureate of the International Academy of Humanism. He was a two-time winner of the Pulitzer Prize for General Nonfiction (for On Human Nature in 1979, and The Ants in 1991) and a New York Times bestselling author for The Social Conquest of Earth, Letters to a Young Scientist, and The Meaning of Human Existence.

Wilson's work received both praise and criticism during his lifetime. His 1975 book Sociobiology: The New Synthesis was a particular flashpoint for controversy, and drew criticism from the Sociobiology Study Group. Wilson's interpretation of the theory of evolution resulted in a widely reported dispute with Richard Dawkins about multilevel selection theory. Examinations of his letters after his death revealed that he had supported the psychologist J. Philippe Rushton, whose work on race and intelligence is widely regarded by the scientific community as deeply flawed and racist.

Edward Osborne Wilson was born on June 10, 1929, in Birmingham, Alabama. He was the only child of Inez Linnette Freeman and Edward Osborne Wilson Sr. According to his autobiography, Naturalist, he grew up in various towns in the Southern United States which included Mobile, Decatur, and Pensacola. From an early age, he was interested in natural history. His father was an alcoholic who eventually committed suicide. His parents allowed him to bring home black widow spiders and keep them on the porch. They divorced when he was seven years old.

In the same year that his parents divorced, Wilson blinded himself in his right eye in a fishing accident. Despite the prolonged pain, he did not stop fishing. He did not complain because he was anxious to stay outdoors, and never sought medical treatment. Several months later, his right pupil clouded over with a cataract. He was admitted to Pensacola Hospital to have the lens removed. Wilson writes, in his autobiography, that the "surgery was a terrifying [19th] century ordeal". Wilson retained full sight in his left eye, with a vision of 20/10. The 20/10 vision prompted him to focus on "little things": "I noticed butterflies and ants more than other kids did, and took an interest in them automatically." Although he had lost his stereoscopic vision, he could still see fine print and the hairs on the bodies of small insects. His reduced ability to observe mammals and birds led him to concentrate on insects.

At the age of nine, Wilson undertook his first expeditions at Rock Creek Park in Washington, D.C. He began to collect insects and he gained a passion for butterflies. He would capture them using nets made with brooms, coat hangers, and cheesecloth bags. Going on these expeditions led to Wilson's fascination with ants. He describes in his autobiography how one day he pulled the bark of a rotting tree away and discovered citronella ants underneath. The worker ants he found were "short, fat, brilliant yellow, and emitted a strong lemony odor". Wilson said the event left a "vivid and lasting impression". He also earned the Eagle Scout award and served as Nature Director of his Boy Scouts summer camp. At age 18, intent on becoming an entomologist, he began by collecting flies, but the shortage of insect pins during World War II caused him to switch to ants, which could be stored in vials. With the encouragement of Marion R. Smith, a myrmecologist from the National Museum of Natural History in Washington, Wilson began a survey of all the ants of Alabama. This study led him to report the first colony of fire ants in the U.S., near the port of Mobile.

Wilson said he went to 15 or 16 schools during 11 years of schooling. He was concerned that he might not be able to afford to go to a university, and he tried to enlist in the United States Army, intending to earn U.S. government financial support for his education. He failed the Army medical examination due to his impaired eyesight, but was able to afford to enroll in the University of Alabama, where he earned his Bachelor of Science in 1949 and Master of Science in biology in 1950. The next year, Wilson transferred to Harvard University.
