1857                585 Broadway, New York, New York.

Hall & Fredericks (John Bishop Hall & Charles DeForest Fredericks) was recorded in an Advertisement that ran three times from February 21 to 28, 1857 in the New York Daily Tribune  (New York, New York).  Hallotypes—These Beautiful Portraits are taken by J. B. Hall, the inventor and patentee, only at the Gallery of Hall & Fredricks, No. 585 Broadway, opposite the Metropolitan Hotel.

The partnership between Hall & Fredericks has not been recorded to my knowledge in other photographic publications.  See Craig’s Daguerreian Registry for more information on John Bishop Hall.
