Nighthawks is a 1942 oil on canvas painting by Edward Hopper that portrays people in a downtown diner late at night as viewed through the diner’s large glass window.
Also portrayed are the exteriors of the urban structures across the street from the diner.
It has been described as Hopper’s best-known work  and is one of the most recognizable paintings in American art.
Within months of its completion, it was sold to the Art Institute of Chicago on May 13, 1942, for $3,000.
It has been suggested that Hopper was inspired by a short story of Ernest Hemingway’s, either “The Killers”, which Hopper greatly admired,  or from the more philosophical “A Clean, Well-Lighted Place”.
In keeping with the title of his painting, Hopper later said, Nighthawks has more to do with the possibility of predators in the night than with loneliness.
