Born Ina Rosenberg, Balin is a tall, slim brunette with the looks of a warm-hearted runway model. She debuted in the '50s on the Perry Como TV show, leading to work on Broadway in Compulsion and A Majority of One. Discovered by Hollywood producers, she made her film debut as Anthony Quinn's daughter in The Black Orchid (1959). In 1961 Balin was voted International Star of Tomorrow by the Hollywood Foreign Press Association, by which time she was considered one of 20th Century Fox's most promising young talents. She later left the studio; her career never achieved the heights of her early promise. Balin toured Vietnam in 1970 with a U.S.O. show; there she visited An Lac, a Saigon orphanage. Her association with An Lac led her to be among the ground personnel helping to evacuate Vietnamese and Asian-American orphans at war's end in 1975, after which she adopted three of the children. This experience was dramatized in The Children of An Lac (1980), a TV movie in which Balin played herself.
