This 1807 portrait of Rubens Peale by Rembrandt Peale hangs in the National Portrait Gallery in Washington, DC.
"Rubens Peale was one of the children of artist and naturalist Charles Willson Peale, who named most of his children after painters and scientists. Rubens was named after the seventeenth-century Flemish painter Peter Paul Rubens. Unlike his older brothers, Raphaelle and Rembrandt, Rubens did not become an artist but followed the family's other business: operating museums of art and science. When his father retired, Rubens became manager of the family's famous Philadelphia Museum. In 1825 he established his own Peale Museum in New York City and for a brief time also managed his brother Rembrandt's museum in Baltimore.Rubens Peale with a Geranium can be seen here: The Portrait Gallery: Rubens Peale
This portrait by his older brother Rembrandt emphasizes Rubens's eyeglasses (he was very nearsighted), as does his more famous 1801 painting, Rubens Peale with a Geranium (National Gallery of Art)." -- National Portrait Gallery
