Boy on a String is the inspirational memoir of Joe Jacoby who worked in the early days of live TV and went on to become a pioneering filmmaker.

Jacoby has never before revealed that his childhood was spent in foster homes and institutions. A New York University film school colleague of Martin Scorsese, Jacoby survived a childhood wrought with abuse and neglect. His mother's unpredictable and sometimes dangerous behavior forced friends to commit her, which then led Jacoby to grow up in seven foster homes in Brooklyn, and two institutions (one for emotionally disturbed children). Yet, propelled by the power of his dreams, Jacoby came to realize his passion for puppetry and movies and made his first feature at the age of twenty-seven (now in the Museum of Modern Art's permanent archives). He also recounts, often with hilarity, his dealings with the last of the movie moguls, Joseph E. Levine.
