(1895–1973), actor. Born in Salisbury, North Carolina, he studied law before making his New York acting debut as a Young Man in The Morris Dance (1917), then played several other supporting roles prior to becoming the leading man in dozens of plays, though never in a major hit. The tall, dark-haired, classic-featured actor gave highly praised performances as Aaron Winterfield, the mountaineer who inherits a fortune, in The Mountain Man (1921); Eugene Thorne, the loyal illegitimate son, in The Love Child (1922); Tony Blunt, the explorer, in Quarantine (1924); and Janos, the virtuous forester, in Belasco's Mima (1928). Following a long career in films, Blackmer came back to Broadway, where once again he was awarded good roles in mediocre plays. His luck changed dramatically in 1950 when he portrayed the failed, alcoholic Doc in Come Back, Little Sheba and won a Tony Award for this performance. His last Broadway appearance was as Paul Cleary, the accused's attorney, in A Case of Libel (1963).
