Ingeborg Hermine "Inge" Morath (Austrian German: [ˈɪŋɛbɔrɡ ˈmoːraːt] ^ⓘ; 27 May 1923 – 30 January 2002) was an Austrian photographer. In 1953, she joined the Magnum Photos Agency, founded by top photographers in Paris, and became a full photographer with the agency in 1955. Morath was the third wife of Pulitzer Prize-winning playwright Arthur Miller; their daughter is screenwriter/director Rebecca Miller.

Morath was born in Graz, Austria, to Mathilde (née Wiesler) and Edgar Morath, scientists whose work took them to different laboratories and universities in Europe during her childhood. Her parents had converted from Catholicism to Protestantism. First educated in French-speaking schools, Morath relocated in the 1930s with her family to Darmstadt, a German intellectual center, and then to Berlin, where Morath's father directed a laboratory specializing in wood chemistry. Morath was registered at the Luisenschule near Bahnhof Friedrichstraße.

Morath's first encounter with avant-garde art was the Entartete Kunst (Degenerate Art) exhibition organized by the Nazi Party in 1937, which sought to inflame public opinion against modern art. "I found a number of these paintings exciting and fell in love with Franz Marc's Blue Horse", Morath later wrote. "Only negative comments were allowed, and thus began a long period of keeping silent and concealing thoughts."

After finishing high school, Morath passed the Abitur and was obliged to complete six months of service for the Reichsarbeitsdienst (Reich Labour Service) before entering Berlin University. At university, Morath studied languages. She became fluent in French, English and Romanian in addition to her native German (to these she later added Spanish, Russian and Chinese). "I studied where I could find a quiet space, in the University and the Underground stations that served as air-raid shelters. I did not join the Studentenschaft (Student Body)."

Toward the end of World War II, Morath was drafted for factory service in Tempelhof, a neighbourhood of Berlin, alongside Ukrainian prisoners of war.

During an attack on the factory by Russian bombers, she fled on foot to Austria. In later years, Morath refused to photograph war, preferring to work on stories that showed its consequences.

After the war, Morath worked as a translator and journalist. In 1948, she was hired by Warren Trabant, first as Vienna Correspondent and later as the Austrian editor, for Heute, an illustrated magazine published by the Office of War Information in Munich. Morath encountered photographer Ernst Haas in post-war Vienna, and brought his work to Trabant's attention. Working together for Heute, Morath wrote articles to accompany Haas' pictures. In 1949, Morath and Haas were invited by Robert Capa to join the newly founded Magnum Photos in Paris, where she started as an editor. Working with contact sheets sent into the Magnum office by founding member Henri Cartier-Bresson fascinated Morath. "I think that in studying his way of photographing I learned how to photograph myself, before I ever took a camera into my hand."

Morath was briefly married to the British journalist Lionel Birch and relocated to London in 1951. That same year, she began to photograph during a visit to Venice. "It was instantly clear to me that from now on I would be a photographer", she wrote. "As I continued to photograph I became quite joyous. I knew that I could express the things I wanted to say by giving them form through my eyes." Morath applied for an apprenticeship with Simon Guttman, who was then an editor for Picture Post and running the picture-agency Report. When Guttman asked what Morath wanted to photograph, and why, she answered that "after the isolation of Nazism I felt I had found my language in photography." After Morath had spent several months working as Guttman's secretary, she had an opportunity to take photographs. She sold her first photographs - of opening nights, exhibitions, inaugurations, etc. - under the pseudonym "Egni Tharom", her names spelled backwards.
