Dr. David Livesey (/ˈlɪvsi/) is a fictional character in the 1883 novel Treasure Island by Robert Louis Stevenson. As well as doctor, he is a magistrate, an important man in the rural society of southwest England, where the story opens; his social position is marked by his always wearing a white wig—even in the harsh conditions of the island on which the adventure takes place. Some years previously, he had fought in the Battle of Fontenoy, and was wounded in action during the battle.
