Edward Gibbon was born in 1737 in Putney, England, and was the only child of his parents to survive infancy. Although his education was frequently interrupted by ill health, his knowledge was far-reaching. His brief career as an undergraduate at Magdalen College, Oxford, ended when he joined the Catholic Church. His father sent him to Lausanne, in Switzerland, where, while studying Greek and French for the next five years, he re-joined the Protestant Church. In 1761 he published his Essai sur l'étude de la Littérature; the English version appeared in 1764. Meanwhile, Gibbon served as a captain in the Hampshire Militia until 1763, when he returned to the Continent. It was while he was in Rome in 1764 that he first conceived the work that was eventually to become The History of the Decline and Fall of the Roman Empire.

In 1774, after the death of his father, Gibbon settled in London and was elected to Parliament where he sat for the next eight years, although he never once spoke in the Commons. He also took his place among the literary circles of London. The first volume of his famous History was published in 1776; it was highly praised for its learning and style but incurred some censure for its treatment of the early Christians. The second and third volumes appeared in 1781 and the final three, which were written in Lausanne, in 1788. He died while on a visit to his friend, Lord Sheffield, who posthumously edited Gibbon's autobiographical papers and published them in 1796.
