Between 1948 and 1954 Smith photographed for
Life magazine a series of
photo essays with a
humanist perspective which laid the basis of modern photojournalism, and which were, in the estimate of
Encyclopædia Britannica, "characterized by a strong sense of empathy and social conscience." In August 1948 Smith photographed Dr. Ernest Ceriani in the town of
Kremmling, Colorado, for several weeks, covering the doctor's arduous work in a thinly populated western environment, grappling with life and death situations. (One of the most vivid images shows Ceriani looking exhausted in a kitchen, having performed a
Caesarean section during which both mother and baby died.) It has been described by Sean O'Hagan as "the first extended editorial photo story". Smith also travelled to Wales where he photographed a series of studies of miners in
South Wales Valleys. Critics have compared Smith's work to similar studies made by
Bill Brandt. From Wales, Smith travelled to Spain where he spent a month in 1950, photographing the village of
Deleitosa,
Extremadura, focusing on themes of rural poverty. In 1951, Smith persuaded
Life editor Edward Thompson to let him do a photo-journalistic profile of
Maude E. Callen, a black nurse midwife working in rural South Carolina. For weeks Smith accompanied Callen on her exhausting schedule, rising before dawn and working into the evening. The essay
Nurse Midwife was published in
Life on December 3, 1951. It was well received and resulted in thousands of dollars in donations to create the Maude Callen Clinic, which opened in
Pineville, South Carolina in May 1953, with Smith present at the ceremony. In 1954, Smith photographed an extensive photo-essay about the work of
Albert Schweitzer at his clinic at
Lambaréné in
Gabon, West Africa. It was later revealed that one of his most famous images had been extensively manipulated. Smith made many layouts of his Schweitzer pictures which he submitted to
Life, but the final layout of the story published on November 15, 1954, entitled
A Man of Mercy, angered Smith because editor
Edward Thompson used fewer pictures than Smith wanted, and Smith thought the layout crude. He sent a formal 60-day notice of resignation letter to
Life in November 1954. After leaving
Life magazine, Smith joined the
Magnum Photos agency in 1955. There he was commissioned by
Stefan Lorant to produce a photographic profile of the city of
Pittsburgh. The project was supposed to take him a month and to produce 100 images. It ended up occupying more than two years and producing 13,000 photographic negatives. The intended book was never delivered to Lorant, and Smith's obsessive work was bailed out by money from Magnum, causing strain between Smith and the photo-journalist collective. ==Jazz Loft Project==
