James (Jimmy) Gibson Powers was Hiram Powers’s first child. He died from a brain tumor in 1838, when he was only four years old. Shortly after the boy died, Powers took a cast of his son’s face to preserve his likeness and perhaps use as a model for a bust. Some of the child’s eyelashes, eyebrows, and hair are embedded in the plaster, making the tragedy of his death real to viewers of this piece more than a century later.
