Identification of the builder (note to follow).
The builder was identified in an article in the Daily Oklahoman, Sunday, January 12, 1908, that announced the dedication services for the temple "next Friday and Saturday": "Prof. W. Gray has arranged an elaborate musical program for the occasion and will have charge of the choir. A new Kimball pipe organ will be used."
According to the temple's history webpage, "By 1951, Temple membership reached 250 families and we were again in need of more space. Land for a new building was given by Erna and Julius Krouch. Over the protests of many who felt that 4901 North Pennsylvania was too far out in the country, ground was broken for a new building on February 28, 1954. Temple B'nai Israel was dedicated on September 11, 1955." The fate of the 1908 building is not stated, and there is no mention of an organ in either building.
