Louise Glaum was an American actress. Known for her roles as a vamp in silent era motion picture dramas, she was credited in her early career with giving one of the best characterizations in such parts.

A femme fatale, sometimes called a maneater, Mata Hari, or vamp, is a stock character of a mysterious, beautiful, and seductive woman whose charms ensnare her lovers, often leading them into compromising, deadly traps. She is an archetype of literature and art. Her ability to enchant, entice and hypnotize her victim with a spell was in the earliest stories seen as verging on supernatural; hence, the femme fatale today is still often described as having a power akin to an enchantress, seductress, witch, having power over men. Femmes fatales are typically villainous, or at least morally ambiguous, and always associated with a sense of mystification, and unease.
