Oil portrait of George Philip Cammann, M.D., circa 1860s attributed to artist Thomas Hicks who was a distinguished portraitist in NYC in the later part of the nineteenth century. Note the characteristic light on the face and hands in portraits painted by Hicks. His portraits also used the portrait d'appart style, portraying the subject with objects associated with his daily life. In the detail on the right is Dr. Cammann's stethoscope held in his right hand with books by Laennec, Stokes and Alison shown on the table. This portrait was given to the New York Academy of Medicine by the family for the opening of their new library in 1879 and was thereafter displayed in the Academy's Museum Room. The oil portrait is likely a posthumous painting (Dr. Cammann died in 1863), commissioned by the family to now document the stethoscope he invented in 1852. Although there are three books displayed in the oil portrait by authors associated with auscultation and stethoscopy, Flint was not one of these authors, perhaps reflecting the early criticism by Dr. Flint of the Cammann binaural stethoscope.
