Louis Agassiz. Autographed Carte-de-visite. Ca. 1860. Studio of John Adams Whipple, 96 Washington Street, Boston. Collection of Christoph Irmscher, Bloomington, Indiana.
The undated portrait shows Louis Agassiz in his fifties, presumably in the parlor of his house on Quincy Street in Cambridge, in a characteristically imperial pose, his broad, well-nourished face half-smilingly turned towards the viewer.
