John Ebenezer Esslemont (1874-1925), was a prominent British Bahá'í from Scotland. He was the author of the well-known introductory book on the Bahá'í Faith, Bahá'u'lláh and the New Era, which is still in circulation. He was named posthumously by Shoghi Effendi a Hand of the Cause, and as one of the Disciples of `Abdu'l-Bahá.

Background
Esselmont's Baha'u'llah and the New Era has been translated into numerous languages. A key, complementary introduction to the Bahá'í Faith, Shoghi Effendi, Guardian of the Bahá'ís encouraged its translation, publication and distribution.
