Noted photojournalist Cornell Capa, the founder of the International Center of Photography, first on the staff of Life magazine and then a member of Magnum Photos, died Friday at the age of 90. Capa, who had Parkinson’s disease, died at his New York City home, the center said, according to the Associated Press.

Capa was a Life magazine staff photographer from 1946 to 1954. He later joined the Paris-based Magnum agency founded by his brother Robert Capa, Henri Cartier-Bresson and others. He served as president of Magnum for four years.

Cornell Capa was best known for his photo coverage on social topics. During the 1960s, he also produced notable picture essays on the Russian Orthodox Church, Moscow Ballet School, Israel in the 1967 Six Day War, and the political campaigns of John and Robert Kennedy, Nelson Rockefeller and Adlai Stevenson.

Capa offered hundreds of exhibitions on the history of photojournalism and the work of some 2,500 photographers. After retiring in 1994, he retained the title of founding director emeritus.

“Cornell was a singular force in the world of photography, opening our eyes to the power of the photographic image as an agent of change,” the center said in a statement, quoted by the A.P.

Capa’s books included “Farewell to Eden” in 1964, “The Andean Republics,” 1966; “The Concerned Photographer,” 1968; “Jerusalem, City of Mankind,” 1974, and “Capa & Capa: Brothers in Photography,” 1990.

“I am not an artist, and I never intended to be one,” he wrote in the 1992 book “Cornell Capa: Photographs.” “I hope I have made some good photographs, but what I really hope is that I have done some good photo stories with memorable images that make a point, and, perhaps, even make a difference.”

Capa leaves no immediate survivors. A private burial ceremony will take place but a memorial service will also be held on September 10 in New York.
