The American painter and naturalist Charles Willson Peale named most of his children after noted artists or scientists. Some of them took up the interests of their father, Rembrandt became a noted portrait painter, and Rubens a botanist and later in life a still life painter.
Here, a young Rembrandt Peale paints a portrait of his 17 year old brother Rubens holding his prize specimen of a geranium — at the time an exotic plant, not native to the Americas — supposedly the first grown on the continent. Rembrandt has given the plant a careful and portrait-like treatment to honor his brother’s accomplishment.
