Burton Egbert Stevenson,
American Men of Mind
“ Perhaps no American actor ever had a more remarkable career than William Warren. Born in 1812, the son of a player of considerable reputation, his first appearance was at the age of twenty. For twelve years his history was that of most other struggling actors, but in 1846 he became connected with the Howard Athenæum at Boston, where he remained for thirty-five years, retiring permanently from the stage in 1882. ”
