Edmund Bailey O'Callaghan

Edmund Bailey O'Callaghan, (probably 27 February 1797 – 29 May 1880) was an Irish doctor, historian and journalist.

Career
Born in Mallow, County Cork, Ireland, he studied medicine in Paris and immigrated to Lower Canada in 1823 where he became involved in the political reform movement of the Parti patriote. He was registered to practice medicine in Lower Canada on 16 October 1827.

On the death of Daniel Tracey, owner of the Montreal Vindicator newspaper, in 1832 O'Callaghan became the editor and brought in Thomas Storrow Brown to work on the paper. They proved to be an irreducible adversary of Lord Gosford and the status quo. In 1834, O'Callaghan was elected to the Legislative Assembly of Lower Canada for Yamaska. In office, he was a close supporter of Louis Joseph Papineau.

In 1837, during the Lower Canada Rebellion, a mandate of arrest was issued against him, and he sought refuge at Saint-Denis, then crossed the United States border with his friend, Louis-Joseph Papineau. Later, O'Callaghan became secretary-archivist of the State of New York, and died there in 1880.
