For Good of Mankind

From Bahaikipedia

August Forel is well-known among Bahá'ís as the recipient of one of the most weighty Tablets ever written by 'Abdu'l-Bahá. This book is an original and comprehensive study of the great Swiss scientist in his relationship to the Bahá'í Faith and particularly his activities as a Bahá'í during the last ten years of his life. It is based on entirely new research, including papers specially made available from Forel's family and the extensive library holdings of Forel's works and papers in Switzerland.
