Martha Root

Martha Louise Root was an American traveling teacher of the Baháʼí Faith in the early 20th century. From the declaration of her belief in 1909 until her death thirty years later, she went around the world four times. Shoghi Effendi, then head of the Baháʼí Faith, called her "the foremost travel teacher in the first Baháʼí Century", and named her a Hand of the Cause posthumously. Known for her numerous visits with heads of state and other public figures, of special importance was her interaction with Queen Marie of Romania, considered the first royal to accept Baháʼu'lláh.
