Here is a photograph of C T Russell in his study at the Pittsburgh Bible House c. 1906. Notice the picture on the wall in the top left hand corner of this photograph.
If you look very closely, below is the photograph under discussion. It is a picture taken of the workers at the Bible House. I originally had two copies, one marked 1899 and the other 1902. Both came from a relative of W E Van Amburgh. As to which is the correct year, a lot would depend on when the Henninges were in America, between visits to Britain, then Germany, and finally Australia.
Bernhard researched the picture and provided the following information which clearly establishes the correct year as 1902 (or very shortly thereafter):
You see on the group photo brother William Van
Amburgh and left brother George Garman. Both became members of the Bible House
family in autumn 1900. So the photo couldn’t be taken before 1900.
Ernest and Rosa (Rose) Henninges were in England
from April 1900 till November 1901 and than he came back to
Pittsburgh. They stayed there till June 1903; than they went to
Germany. So the photo couldn’t be taken before November 1901.
Otto Koetitz and his wife Jennie succeeded Henninges
in November 1903 in Germany. Otto was a coworker in Bethel from 1896 followed
by his wife in 1900.
Albert Williamson became a member of the Bible House
staff in 1899. Harriet Stark (who married him in 1905) and her mother Britee C.
Stark began to work in the Bethel in 1900.
Laura Whitehouse lived also there since 1900.
Johannes Gotthold Kuehn came also in 1900 to the
Bible House as a part-time worker. His wife Ottilie Friederike and son Alfred
followed in 1902.
So this brings us to the date of 1902, maybe early 1903.
Subsequent to this article being written originally,
Bernhard incorporated this material into his book on the Bible House.
