The Night Watch by Rembrandt van Rijn, 1640 - 1642. Rembrandt painted The Militia Company of Captain Frans Banning Cocq between 1640 and 1642. This picture was called the Nachtwacht by the Dutch and the Night Watch by Sir Joshua Reynolds.
Rembrandt Van Rijn - not a famous person, but amazing. I saw it in the Rijks Museum in Amsterdam.
