Unidentified photographer (Brazil) 1844 (handwritten) Commodore Peter Turner (1803-1871) in US Navy dress uniform
Daguerreotype Private collection of Richard B. Hall Taken at Rio de Janeiro in 1844 while serving as a lieutenant in the Brazil Squadron under his uncle, Commodore Daniel Turner (1794-1850). Daguerreotype is housed in a simple brown case with blue embossed mat, with an inked note stating the time and place of the photograph, and declaring it a "poor likeness."
Possibly by Charles DeForest Fredricks but this requires confirmation.
