Shigeo Sasaki,

87, whose daughter was an atomic bomb victim who became famous for the paper cranes she folded, died Tuesday in Tokyo of a brain tumor.

Mr. Sasaki devoted his life to campaigning for peace after his 12-year-old daughter Sadako died in 1955 of radiation-related leukemia that she developed after the United States dropped the atomic bomb on Hiroshima 10 years earlier. Mr. Sasaki, a barber from Hiroshima, retold her story to school children around the nation.

Sadako made cranes on her hospital bed, inspired by a Japanese legend that says anyone who makes 1,000 paper cranes would be granted a wish. She died before finishing the cranes, but her story led children all over Japan to raise money for a statue of her in Hiroshima.
