*Resusci Anne, also known as Rescue Anne or CPR Annie, is a training mannequin used for teaching cardiopulmonary resuscitation (CPR) to both emergency workers and members of the general public. The distinctive face of Resusci Anne was based on L’Inconnue de la Seine, the death mask of an unidentified young woman reputedly drowned in the Seine River around the late 1880s. [from itthing.com]
