English physician; born at Lisbon 1738; died in London Nov., 1816. He came of a medical family, his grandfather, father, and two uncles having all been physicians. He was instructed in general literature and philosophy by the Fathers of the Oratory, a body of learned men then highly popular in Portugal. Having chosen medicine as his profession, he was sent to the University of Bordeaux, France, where he remained for two years. He then removed to Leyden, and, completing the three years' residence which the statutes of the university required, received his M.D. degree Aug. 31, 1758. Eventually he settled in London, was admitted a licentiate of the Royal College of Physicians (March 25, 1771), and was introduced into practise by his uncle, Dr. de la Cour, who soon after withdrew to Bath.

Sequira gained a high reputation among his countrymen resident in England. He held the honorary appointment of physician extraordinary to the Prince Regent of Portugal, and was physician to the Portuguese embassy at the Court of St. James. He lived to an advanced age, and at the time of his death was the oldest licentiate of the Royal College of Physicians.
