One cold sunny morning in December 2018, Gerhard Steidl drove from New York City to see John Cohen at his rambling home in upstate Putnam Valley. The purpose of the visit was to pick up originals to be scanned for Cohen’s Look up to the Moon, his book of photos from Morocco in 1955 and published by Steidl in 2019. But in the organized chaos of Cohen’s barn-cum-studio they stumbled across another group of prints from across his 60-year career: “I didn’t know what to do with them,” he recalls, “They weren’t a book or an exhibit, or for sale. They were not of one subject.” To Cohen’s surprise and delight, Steidl took the boxes under his arm, and the photos now appear for the first time here in Do Not Disturb My Waking Dream, Cohen’s most lyrical and personal book, as well as his last.
