Mrs. Mary Alice Duncan, Oprah's fourth-grade teacher at Wharton Elementary in Nashville, was first on the list. "I ran home the first day of the fourth grade to tell my dad that I had the best teacher that anybody could ever have. Her name was Mrs. Duncan," Oprah said. "I wanted to be a fourth grade teacher because of Mrs. Duncan."
After their tearful reunion, Oprah asked Mrs. Duncan if she was her favorite student that year. "Oh, of course...but I couldn't let anybody know," Mrs. Duncan said. "Oprah is one I couldn't forget."
