A research foundation here plans to display 223 photographs in August that a U.S. scientist took in Hiroshima and Nagasaki after the U.S. atomic bombings of the cities in 1945.

Paul Henshaw, a U.S. scientist who took part in the Manhattan Project to develop atomic bombs during World War II but later became a peace activist, took the pictures between 1945 and 1947. He died in 1992 at age 90.

His son, Robert, 71, donated the photos -- most of them are color -- last year to the Radiation Effects Research Foundation, which operates laboratories in Hiroshima and Nagasaki.
