Barry Edward O'Meara, an Irish surgeon, born about 1780, died in London, June 3, 1836. He entered the army at an early age, and served several years in Sicily, Egypt, and Calabria, as assistant surgeon to the 32d regiment. He was afterward surgeon in the navy, and was appointed to the Bellerophon in July, 1815, when Napoleon came on board that ship as a prisoner. At the request of Napoleon, O'Meara accompanied him to St. Helena in the capacity of medical attendant; but on account of a rupture with Sir Hudson Lowe in regard to the treatment of Napoleon, he returned to England in 1818. Having accused Sir Hudson Lowe before the admiralty of cruel and arbitrary conduct, his name was erased from the list of naval surgeons. He afterward acted with the extreme liberals, and was a partisan of O'Connell. He published "Letters from the Cape of Good Hope;" "Letters from St. Helena;" " Letters from Count Las Cases," with a preliminary discourse; " Exposition of the Treatment of Napoleon Bonaparte;" a translation of the " Memoirs of Napoleon " by himself; and " A Voice from St. Helena, or Napoleon in Exile".
