I've lived in Minnesota most of my life, and although I grew up seeing various versions of this iconic photograph, I never knew of its Minnesota origin:
Eric Enstrom was a Swedish American photographer who lived and worked in the mining town of Bovey. Around 1920 (some accounts date the event to 1918), an itinerant salesman named Charles Wilden visited his studio. Impressed by what he recognized as kindness in the man's face, Enstrom asked Wilden to pose for a picture. He had Wilden clasp his hands and bow his head, as in prayer, while seated at a table with an arrangement of household objects, including a book, a loaf of bread, and a bowl of soup. He called the photograph "Grace."Read the full article here.
Enstrom composed "Grace" to represent survival in the face of hardship. He later connected it to World War I and the heavy toll the trenches of Europe had taken on American lives, as well as the rationing faced by Minnesotans on the home front. In a 1961 interview, he explained his intention to capture an image that would inspire thankfulness in people who had endured privations during the war. By highlighting Wilden's devout posture and humble surroundings, he aimed to evoke the spirit of religious faith, thankfulness, and humility he associated with many of the newly arrived European immigrants to Minnesota.
