Constance Collier was born Laura Constance Hardie in Windsor, Berkshire on 22nd January, 1878. She was the daughter (and only child) of Auguste Cheetham Hardie and his wife Eliza Georgina (Collier), who were both professional actors though neither enjoyed a career of any great note. Eliza came from a long line of theatrical performers, whilst Auguste (known as 'Cheet' to his familiars) came from a very different tradition, having broken away from his wealthy merchant family in order to take to the stage.
