The subject is the Philadelphia portraitist John Neagle (1796-1865). Dickinson exhibited this miniature at the Pennsylvania Academy of the Fine Arts in 1830. The attribution to J. R. Smith is erroneous; Garrett C. Neagle was the subject's son.

Descended in the family of the artist; to the Schwarz Gallery, Philadelphia, ca. 1990. I saw the piece at the Schwarz Gallery in about 1996, when the late owner, Robert Schwarz acquired it, but he was not ready to sell it, thinking that he might mount an exhibition of Philadelphia portrait miniatures. I reminded Mr. Schwarz's son of the piece last year (late 2005) and asked if it was yet available, which it was.
