Hugh Swinton Legaré (; January 2, 1797 – June 20, 1843) was an American lawyer, diplomat and politician from South Carolina who served as the 16th United States Attorney General under President John Tyler.
Legaré served as Attorney General of South Carolina from 1830 to 1832 before President Andrew Jackson appointed him as the acting minister to the new Kingdom of Belgium. On his return to the United States, he was elected to represent Charleston in the United States House of Representatives but lost re-election to Isaac E. Holmes.
Following the 1841 death of President William Henry Harrison and the resignation of Whigs from the cabinet, Legaré was named United States Attorney General by John Tyler. He served as Attorney General until his death in office on June 20, 1843. For the final month of his life, Legaré also served as United States Secretary of State ad interim following the resignation of Daniel Webster.
Legaré was born in Charleston, South Carolina, of Huguenot and Scottish ancestry.
Partly due to his inability to share in the amusements of his fellows, as a result of a vaccine-related deformity suffered before he was five that permanently stunted the growth and development of his legs; Legaré was an eager student and was president of the Clariosophic Society at the College of South Carolina (now University of South Carolina at Columbia), from which he graduated in 1814 with the highest rank in his class and with a reputation for scholarship and eloquence.
After graduation, he studied the law for three years, did advanced work in Paris and Edinburgh in 1818 and 1819 and in 1822 was admitted to the South Carolina bar.
After practicing for a time in Charleston, he became a member of the South Carolina House of Representatives, serving between 1820 and 1821 and then again between 1824 and 1830. He also founded and edited the Southern Review between 1828 and 1832.
From 1830 until 1832 he was the Attorney General of South Carolina, and he supported states' rights, he strongly opposed nullification. He was Attorney General until he was appointed chargé d'affaires to Brussels in 1832, serving there until 1836. In 1838, he was elected as a member to the American Philosophical Society.[1]
On his return he was elected to the 25th Congress as a Democrat, but failed in a re-election bid the following term. In 1841 President John Tyler named him Attorney General of the United States and he served in that office until his death. He also served as Secretary of State ad interim from May 8, 1843, until his death.
He died in Boston while attending ceremonies for the unveiling of the Bunker Hill Monument. He died, by "internal strangulation..the twisting of the intestine upon itself."[2] He was first interred in Mount Auburn Cemetery in Cambridge, Massachusetts, and was later re-interred in Magnolia Cemetery in Charleston. The USCGC Legare, which is a medium endurance cutter, was named in his honor.
