Arnold Daly (October 22, 1875 – January 13, 1927) was an American actor, playwright and producer. He was the father of actress and Algonquin Round Table personality Blyth Daly.
He was born Peter Christopher Arnold Daly in Brooklyn, New York, the son of Irish parents Joseph J. Daly and Mary Arnold. His father was an importer of wood for use in cabinet construction. After being expelled from four public schools, he finally left parochial school following the death of his father in 1886. He made his first appearance as an actor in The Jolly Squire, 1892.
During his career he claimed credit for a hundred plays, although many were either adapted from foreign plays or written by his brother Joseph. He was noted for introducing the early Shaw plays to American audiences, including Candida, Mrs. Warren's Profession and You Can Never Tell. The play Mrs. Warren's Profession was closed after a single showing by the authorities due to its depiction of a prostitute. Shaw was noted for his extremely detailed stage directions, which some actors found overly prescriptive. Daly said "I have acted out every one of Mr. Shaw's stage directions to the letter, as far as I am able, with one exception, and that is where Marchbanks goes 'trotting' across the stage to the fireplace. I'm too heavy to trot as Shaw meant. Three years ago I could have done it, and now perhaps I might do it three nights in six. But I don't dare risk it."
