Toni Wolff, Swiss psychologist and author (d. 1953)
Toni Anna Wolff (18 September 1888 – 21 March 1953) was a Swiss Jungian analyst and a close collaborator of Carl Jung. During her analytic career Wolff published relatively little under her own name, but she helped Jung identify, define, and name some of his best-known concepts, including anima, animus, and persona, as well as the theory of the psychological types. Her best-known paper is an essay on four "types" or aspects of the feminine psyche: the Amazon, the Mother, the Hetaira, and the Medial (or mediumistic) Woman.
