O'meara, Barry Edward
A surgeon, born in Ireland, who accompanied Napoleon to St. Helena, and became his physician, having been surgeon on board the Bellerophon when the emperor surrendered himself; is remembered as the author of "A Voice from St. Helena; or, Napoleon in Exile," a book which from its charges against Sir Hudson Lowe created no small sensation on its appearance (1786-1836).
