From PBS and American Masters - More than four decades of 20th-century America are filtered through Lange's life and lens -- her creations and achievements; her tragedies and losses. Known for her powerful images from the Great Depression; her haunting "Migrant Mother" remains emblematic of that period. In 1936; when photographs of the poverty-stricken mother of seven; stranded in a camp in California; were published; a national awareness began. As America matured into a world power; Lange continued to bear witness -- mass migration; increasing urbanization and the cost of war at home -- bringing subjects alive; transmitting raw emotions and capturing the human condition. This film is made by Dyanna Taylor; Lange's granddaughter; who began her artistic vision; literally; at Lange's feet.
