Best known for her acting career, which began in the early years of the twentieth century and ended in the thirties, Viola Tree was also an opera singer and a theatre manager. She published an autobiography, an etiquette book, and a biography of her husband. She also wrote two plays, one of which was in collaboration with Gerald du Maurier. Neither play was published, but both were produced. Her etiquette book stemmed from the etiquette and advice articles she had written for various magazines and newspapers, including her Sunday advice column.
