September 26. On this date in 1877, Siegfried Schopflocher, a Hand of the Cause of God, was born. The youngest of 18 children, he was raised an Orthodox Jew in Germany, and later became a Bahá’í at Green Acre after having emigrated to Canada.

On September 25, 1936, Shoghi Effendi wrote the following introduction to the National Spiritual Assembly of India...

Visit of Mr. Schopflocher to India
I am addressing you these few lines on behalf of our beloved Guardian to ask you to kindly inform your fellow-members in the Indian N.S.A. of the happy news of the projected visit of dear Mr. Siegfried Schopflocher to India, and to request you to take any step that your Assembly deems advisable in order to make his journey as fruitful and abundant in its results as possible.
Mr. Siegfried Schopflocher is not in need of any introduction, as his long and manifold services to the Cause in America and particularly his generous and unfailing support of the local, national as well as international Baha'i funds, have endeared him to all the friends, whether in the East or in the West.
For many years he has been a member of the American N.S.A. and he contributed no small part in the steady development and consolidation of the Administration ever since the early days of its establishment in the States. He is indeed an outstanding champion of the Administration not only in America but also in the West, and has proved in deeds his profound attachment and loyalty to all its principles, laws and institutions.
His name will be ever associated with the beloved Temple in Wilmette. Had it not been for the continued and whole-hearted support, both financial and moral, which he so generously extended to it, that edifice could have never been reared so steadily and efficiently. The friends will always remember with deep gratitude the eminent services he has rendered the Faith in this connection.
In view of these labours so devotedly accomplished, the Guardian wishes your Assembly to urge the friends to draw full benefit from Mr. Schopflocher's visit to India. He is confident that you will extend to him a most hearty welcome, and will, through association with him, draw fresh strength and inspiration in your arduous labours for the Cause.
