In a mix of documentary, drama, and animation, a new biography of Louisa May Alcott delves into her struggle of writing stories that paid the bills, such as "moral pap for the young" and lurid pulp fiction, versus the tales that captivated her. Additionally, the biography looks at her family's progressive ways and "Little Women." American Masters "Louisa May Alcott: The Woman Behind Little Women" airs at 10 p.m. | Georgia Public Broadcasting
