Mary Martin was one of the greatest stars of her day. Growing up in Texas, she was married early to Benjamin Hagman and gave birth to her first child, Larry Hagman. She was divorced even more quickly. Martin left little Larry with her parents and took off for Hollywood. She didn't make a dent in the movie industry and was lured to New York where she found herself auditioning for Cole Porter. Six years later, she became the Toast of Broadway when she starred in South Pacific. After that, she flew as Peter Pan, yodeled in The Sound of Music, took Hello, Dolly! on the road and shared a four-poster with Robert Preston in I Do! I Do!.
Her personal life was just as interesting and it's all covered in David Kaufman's book, Some Enchanted Evenings: The Glittering Life and Times of Mary Martin.
