From A Dictionary of Irish Artists 1913
Was born in Cork, the son of William Heazle, organist of St. Ann's Church, Shandon. He commenced his art training under William Willes in the Cork School of Art in 1850, and afterwards studied at South Kensington where he showed much promise. He painted chiefly in oils, and did some excellent copies of pictures by Etty. Although offered a good position as a teacher in London he returned to Cork. He painted a number of pictures in his native city, and sent six pictures of domestic and other subjects to the Royal Hibernian Academy in 1861; but not finding his work remunerative he abandoned art and began to study for the medical profession. His health, however, gave way and before he could qualify he died of aneurism of the heart in his father's house, 9 Queen Street, Cork, in 1872.
