Country Doctor - Dr. Ernest Ceriani with Coffee, Cigarette, and Nurse in Hospital Kitchen

After World War II, LIFE magazine assigned staff photographer W. Eugene Smith a human interest story about a doctor in rural America. They sent him to Kremmling, a small and remote town in northern Colorado. His subject: Dr. Ernest Ceriani.

At first, Smith observed Dr. Ceriani and earned the trust of the townspeople. He wrote: 'I spent four weeks living with him. I made very few pictures at first. ... I simply faded into the wallpaper and waited.' The resulting story spanned 11 pages in LIFE's September 20, 1948 edition.

Smith's intimate series depicts Dr. Ceriani as a heroic yet weary figure who made house calls, delivered babies, and tended to the young and old alike. Through Smith's lens, Ceriani carries the weight of the world on his shoulders as the only doctor within 400 miles.

A LIFE compendium later summarized 'Country Doctor' as "an instant classic when published, establishing Smith as a master of the commanding young art form of the photo essay, and solidifying his stature as one of the most passionate and influential photojournalists of the 20th century." As TIME magazine explained in its 2016 compendium '100 Photographs: The Most Influential Images of All Time': "By digging so deeply into his assignment, Smith created a singular, starkly intimate glimpse into the life of a remarkable man. It became not only the most influential photo essay in history but the aspirational template for the form.'"
