Shoghi Effendi appointed Dr. John Esslemont a Hand of the Cause of God.
With the passing of Dr Esslemont Shoghi Effendi was left without qualified administrative assistance. This situation remained in place until the formation of the International Bahá'í Council in 1951. [PP92-95, SETPE1p112]
Shoghi Effendi designated Martha Root as a Hand of the Cause of God posthumously. She had passed away on September 28, 1939 in Hawaii.
Shoghi Effendi called her the ‘archetype of Bahá’í itinerant teachers’, the ‘foremost Hand raised by Bahá’u’lláh since ‘Abdu’l-Bahá’s passing’, ‘Leading ambassadress of His Faith’ and ‘Pride of Bahá’í teachers’. [GPB386]
Elizabeth Martin with Chris Lyons made a film called Retrospective, a memoir of Hand of the Cause John Robarts. It included his reminiscences of the Guardian and of the early days of the Faith in Canada. [HNWE36]
