"

On March 29, 1979, he suffered severe burns in a fire at the Copley Plaza hotel, in Boston, but survived after thirty hours of extensive surgery at Massachusetts General Hospital. Though he was warned that he might never be able to live a normal life again, eight years later he was fit enough to insist on playing tennis nearly every day and to launch a hostile takeover of Viacom.[9] Redstone has discussed the story of surviving the fire as a reflection of his strong determination and will to live.[10]
