Morath divorced Birch and returned to Paris. Her first jobs were stories that did not interest "the big boys." She went to London on an early job to photograph the residents of Soho and Mayfair. Morath's portrait of Mrs. Eveleigh Nash, from that job, is among her best-known works. During the late 1950s Morath traveled widely. She covered stories in Europe, the Middle East, Africa, the United States, and South America. She worked for such publications as "Holiday", "Paris Match", and "Vogue". In 1955 she published "Guerre à la Tristesse", photographs of Spain, with Robert Delpire. This was followed by "De la Perse à l'Iran", photographs of Iran, in 1958. Morath published more than thirty monographs during her lifetime.
