Marion Post Wolcott is best known for the more than 9,000 photographs she produced for the Farm Security Administration (FSA) from 1938 to 1942.1 This work is preserved at the Library of Congress Prints and Photographs Division and also available online. Before Wolcott became a government photographer, she earned her living making photographs for magazines and newspapers. Initially she worked freelance, but, as a staff photojournalist in 1937 and 1938, Wolcott broke gender barriers in the newspaper darkroom. Then she worked for the Farm Security Administration, one of the largest news photography projects in the world. She covered thousands of miles of the United States with her camera to document and publicize the need for federal assistance to those hardest hit by the Great Depression and agricultural blight.
Drawing on her social concerns and her artistic vision to illustrate issues that needed redress, Wolcott produced an extraordinary number of images and her occupation challenged many social morés about the propriety of young women living away from the family home and traveling on their own. Although she worked professionally for only a few years, her artistry and perseverance have inspired many articles, books, and exhibitions and her photographs created a lasting record of American life on the eve of World War II.
