Jo che dipinge (Josephine Hopper) - Edward Hopper

Hopper liked walking around New York at night, looking into lit windows. Room in New York, one of his best paintings, came from doing exactly that: glimpsing a couple in an apartment, not speaking to each other, the woman touching a piano key with one finger. He painted what he saw from the outside.

He grew up in Nyack, a small town on the Hudson River, studied illustration, then moved to Robert Henri's painting class at the New York School of Art. Henri was the central figure of the Ashcan School, which painted American life without prettifying it. Hopper absorbed the directness but not the social energy. His paintings got quieter, more still, more concerned with what people look like when they think nobody is watching.

He went to Paris three times between 1906 and 1910 and came back with Degas and Manet in his head: cropped compositions, angled light, figures caught mid-thought. Then he spent a decade failing commercially, working as an illustrator to pay the bills, and painting watercolours that nobody bought. Success came late. His first solo show was at forty-one.

In 1924 he married Josephine Nivison, a painter who had also studied under Henri. She modelled for nearly every female figure in his paintings, managed his career, and kept detailed records of every work he produced. The marriage was difficult. Both of them had sharp tempers. She engineered his public image as a recluse, which he was, mostly.

Nighthawks, the diner painting, was made in 1942. Jo named it. Hopper admitted he was probably painting the loneliness of a large city, though he was reluctant to say so directly. The diner has no visible door. People have pointed this out for eighty years and nobody has determined whether it was intentional.
