After Kristallnacht, Vishniac and his family were determined to leave Europe, and spent years trying to find a way out., Finally, on December 20, 1940, Vishniac’s family embarked for America. From the safety of New York City, Vishniac tried in vain to use his photographs to bring attention to the plight of Jews in Europe and to inspire some sort of action. He sent prints to President Roosevelt, and organized exhibitions of his work at Columbia University and the YIVO Institute.
After the war, Vishniac worked as a freelance photographer in New York. Working both for Jewish organizations and on his scientific work, Vishniac’s subjects included performers and artists in New York nightclubs, Jewish Displaced Persons Camps, the ruins of Berlin, portraits of Albert Einstein, among many others. No less important than his contribution as an artist, Vishniac was an avid scientist, and made considerable contributions in the field of microscopic photography. His “Living Biology” series, funded by the National Science Foundation, were some of the first films depicting life through a microscope. He is often credited as being one of the pioneers of this field.
