Chinua Achebe [SEP] "Anthills" and paralysis
On 22 March 1990, Achebe was riding in a car to Lagos when an axle collapsed and the car flipped. His son Ikechukwu and the driver suffered minor injuries, but the weight of the vehicle fell on Achebe and his spine was severely damaged. He was flown to the Paddocks Hospital in Buckinghamshire, England, and treated for his injuries. In July doctors announced that although he was recuperating well, he was paralyzed from the waist down and would require the use of a wheelchair for the rest of his life. Soon afterwards, Achebe became the Charles P. Stevenson Professor of Languages and Literature at Bard College in Annandale-on-Hudson, New York; he held the position for more than fifteen years.
