Dunell Cohn was born in Oak Ridge in 1944. Cohn’s father, Waldo, was recruited to work on the Manhattan Project in Chicago in 1942 for his work on radioisotopes at Berkeley and Harvard during the 1930s. Shortly thereafter, he was transferred to Oak Ridge, where he developed a method to separate the fission products from the nuclear reactor. He also pioneered the radioisotope program at Oak Ridge, producing radioisotopes in large quantities that could then be used for medical and biological research. Dunell recalls what it was like growing up as a child at Oak Ridge and describes his father’s effort to desegregate the town by integrating the public school system. He also remembers his father’s love for music and his role in creating Oak Ridge’s symphony orchestra.
