I am unable to confirm my recollection of the Michener-Saturday Evening Post connection. But I did find a couple mentions of his having been an editor for a couple short stints. He was said to have been an orphan, subsequently "adopted" by his biological mother, although that could not be confirmed.They were so poor he had no sports equipment. At ages 17 he ran away from home. He worked in a travelling carnival Yet, if I remember correctly, he gave away over a hundred million dollars. A remarkable achievement in view of his early deprivation. A real life Horatio Alger hero.
