Horst P. Horst (August 14, 1906 – November 18, 1999) was a German-American fashion photographer. The first pictures that carried a Horst credit line appeared in the December 1931 issue of French Vogue. It was a full-page advertisement showing a model in black velvet holding a Klytia scent bottle in one hand with the other hand raised elegantly above it... Horst's real breakthrough as a published fashion and portrait photographer was in the pages of British Vogue... starting with the 30 March 1932 issue showing three fashion studies and a full-page portrait of the daughter of Sir James Dunn, the art patron and supporter of Surrealism. Horst officially moved to the United States in 1940 as he became a citizen in 1942. Enlisting in the United States Army in the same year, he became an Army photographer. In 1945 he was given the assignment of completing a shoot of President Harry S. Truman. From that time on he was honored to photograph every First Lady in the post war period.
