William Archer (1856-1924) was a Scottish writer and theatre critic, based, for most of his career, in London. He was an early advocate of the plays of Henrik Ibsen, and was an early friend and supporter of Bernard Shaw.
In 1878, in accordance with his father's wishes, he moved to London to train as a barrister. He was uninterested in the law, and was by now fascinated with the theatre. He qualified for the bar in 1883, but never practised. He supported himself by working as dramatic critic of The London Figaro, and after he finished his legal studies he moved to The World, where he remained from 1884 to 1906. In London he soon took a prominent literary place and exercised much influence.
