Emanuel Leutze and Worthington Whittredge became close friends the day Whittredge arrived to study in Dusseldorf in 1849. As he recounts in his autobiography, Whittredge was immediately asked to serve as a model for the steersman and for General Washington in Leutze's Washington Crossing the Delaware. They remained constant companions through their years in Europe, and, back in the United States, both artists maintained studios in the Tenth Street Studio Building. In addition to this diploma portrait Leutze painted at least two other portraits of Whittredge.
