What does Smith's rural doctor want to express?

Smith published several groups of thematic photographs in Life magazine, among which Country Doctor became a classic of photography topic because of its "classicality" and "turning point". It is also the most representative of Smith's style. This special topic, published in Life magazine on September 20th, 1948, consists of 28 photos. Ernest Ceriani, the protagonist of the project, is the only doctor in a small town named Kremmling in Colorado, USA. In order to treat patients, he often forgets to eat and sleep, showing lofty dedication.
