F.C. Gundlach was Germany's most famous and prolific fashion photographer, from the 50's to the 80's. He built a huge body of work shooting for Brigitte (a bi-weekly German women's magazine started in 1953 and still around; I think the US equivalent would be something like Cosmopolitan — not Vogue).
