DESC: When Barack Obama learns of the death of his African father, whom he hardly knew, he is compelled to trace his unusual family history. Obama, who became a nationally known figure in 2004 when he gave the keynote address at the Democratic Convention, writes movingly about being raised in Hawaii by his white mother. He goes on to describe his years at Harvard (where he was the first black president of the Harvard Law Review), his illuminating visit to family members in Kenya, and his work as a community activist in Chicago, where he eventually entered Illinois politics.
