For Eakins, portraiture held little interest as a means of fashionable idealization or even simple verisimilitude. Instead, it provided the opportunity to reveal the character of an individual through the modeling of solid anatomical form. This meant that, notwithstanding his youthful optimism, Eakins would never be a commercially successful portrait painter, as few paid commissions came his way. But his total output of some two hundred and fifty portraits is characterized by "an uncompromising search for the unique human being".
