She was born on 21 February 1852, the daughter of an Episcopal clergyman. She married James D. Brittingham in 1886 and attended her first Baha'i study class in 1898. Almost immediately on accepting the Faith she began to travel to share it. In September 1901 she visited 'Abdu'l-Baha in 'Akka. After her visit she wrote a scholarly instructive essay, The Revelation of Baha'u'llah, which was published in 1902 by the Baha'i Publishing Society. Whenever she witnessed a new declaration of faith she would, week after week, send off their letters to 'Abdu'l-Baha, Who on one occasion said laughingly, "Mrs. Brittingham was our Baha'i-maker." One such distinguished person who studied the Faith with her was Dr. Susan Moody, who later rendered heroic services to the Faith as a doctor, educator, and Baha'i teacher in Tihran, Iran. Mrs. Brittingham received the full support of her husband, James, who was not able to accompany her on her teaching trips. She made her second pilgrimage to the Holy Land in October 1909. She continued her traveling for the Faith to the end of her life and, in the home of the Revell sisters in Philadelphia, she dictated 11 letters to Jessie Revell on the evening of 28 January 1924 and then passed away later that same evening.
