Oprah Winfrey has received the Academy of Motion Picture Arts and Science's Jean Hersholt Humanitarian Award, an Oscar statuette given periodically to a film-industry individual for humanitarian efforts. In a teary-eyed acceptance speech at the Academy's annual Governors Awards in Los Angeles Saturday, the former talk-show host, 57, said, "I never imagined myself receiving an Oscar, certainly not for doing what I believe is a part of my calling . . . for what I believe is the essence of why we're all here [which is] to use our lives in service to one another." Her philanthropic efforts include The Oprah Winfrey Foundation and Oprah's Angel Network, and she was instrumental in the passing of the federal National Child Protection Act of 1993.
