His great-grandfather, Robert, was chief justice of South Carolina in 1708, and his father, William, was one of the secret committee of five of the council of safety in Charleston at the beginning of the Revolution. William Hasell studied law with John Rut-ledge, and afterward, in 1774, at the Inner Temple, London. He was one of the thirty native Americans residing in London who petitioned the king against the series of acts of parliament that were the immediate cause of the Revolution. At the beginning of the war he escaped to Bermuda, went thence to Charleston, where he became captain-lieutenant of the ancient battalion of artillery, and fought at Beaufort and in the siege of Savannah. He was admitted to the bar prior to 1783, and from that year till his resignation in December, 1825, was master in chancery. In 1811 he was tried before the state senate on articles of impeachment preferred by Thomas Lehre, senior, but was acquitted.--His son.

He was surgeon-general of the state from 1861 till the close of the war, and during that time made an examination of the Virginia hospitals, for which he was praised by the Confederate congress. In 1865, when Columbia was burned, he lost his house, with valuable collections of paintings, fossils, and minerals. His chief scientific researches were devoted to the description of organic remains from his native state, and include a "Monograph on Fossil Squalidse," in the journal of the Philadelphia academy of sciences, and a " Memoir on Monosaures and the Three AI-lied New Genera," in the "Smithsonian Contributions to Knowledge" (1849).

Many of his scientific articles were republished in France and Germany. His chief literary work, the material for which he was twenty-five years in collecting, is a " Documentary History of the American Revolution; consisting of Letters and Papers relating to the Contest for Liberty, chiefly in South Carolina," covering the years from 1764 to 1782 (3 vols., Columbia, South Carolina, and New York, 1853).
