Aminadab—the bulky, coarse laboratory assistant to Aylmer. He has great mechanical ability, the brawn, so to speak, to the brains of his master, Aylmer.
Aylmer—a superb scholar and scientist. He marries Georgiana, whom he loves, but his devotion to ideal beauty and scientific studies rivals his devotion to his wife. As a result, he seeks to perfect her loveliness by removing from her face a birthmark that he thinks is a “defect.”
Georgiana—the beautiful, newly wedded wife of Aylmer. Born with a birthmark that looks like a small hand on her left cheek, Georgiana wants her husband to love her and admires his pursuit of beauty. She painfully regrets that he finds her beauty marred by the birthmark; as a result, she submits to his experiments to remove the “imperfection.”
Narrator—the distinctive voice, most likely male, that recounts “The Birthmark.” He assumes the formal role of a storyteller, giving the reader warnings and implying correct moral choices.
