Hospital officials said Dzhugashvili died late August 27 at Burdenko military hospital after a prolonged illness.
Her father, Yakov -- Stalin's eldest son -- was a Soviet army officer who historians say died at the Nazis' Sachsenhausen camp in 1943 after Stalin declined to swap him for a captured German general.
Four years ago, Dzhugashvili said that her recollections of her grandfather were "a child's memories - the best and most tender."
She said Stalin had been "very tender" with her because she was a girl.
