Samuel Finley Breese Morse, Captain Demaresque of Gloucester 

"Captain Demaresque of Gloucester" is a portrait painting by Samuel Morse, known for his invention of the telegraph. The painting features a close-up view of Captain Demaresque, a Gloucester, Massachusetts sea captain, in a dark coat with a white cravat. Morse's skill in capturing the details of the sitter's face and clothing is evident in this portrait, a typical example of his work before he became known for his contributions to science. The painting is currently housed at the Princeton University Art Museum (PUAM).
