John F. Vachon (19 May 1914–20 April 1975) was an American photographer.
By 1937 Vachon had looked enough to want to make photographs himself, and with advice from Ben Shahn he tried out a Leica in and around Washington. His weekend photographs of “everything in the Potomac River valley” were clearly the work of a beginner, but Stryker lent him equipment and encouraged him to keep at it.
Vachon became a staff photographer for Life magazine, where he worked between 1947 and 1949, and for over twenty five years beginning in 1947 at Look magazine. When Look closed in 1971 he became a freelance photographer. Read full wikipedia article.
