He was difficult and flamboyant, a shameless self-promoter, bender of the truth and master of reinvention. He was also one of the groundbreaking photographers of the 20th century - a brilliant artist whose body of work spans decades, continents, and the catastrophic fallout from two world wars. Though his pioneering microscopy transformed the nature of science photography, Roman Vishniac is best known for his iconic images of Jewish life in Eastern Europe from 1935 through 1938. Few predicted that less than a decade later, these communities would be wiped out, and Vishniac's photographs would provide the last visual records of an entire world. Now for the first time, his story comes to life as a feature documentary. A retrospective and family saga, VISHNIAC is narrated by Vishniac's daughter Mara. She grew up in his shadow and sought to break free of his grip, only to eventually come around and embrace his legacy.
