The Work of National Geographic Photographer William Albert Allard

William Albert Allard: Five Decades is a photographic memoir that details the 48 years that Allard — who is considered a pioneer of color photography — spent in the field shooting images for National Geographic. As an intern for the magazine back in 1964, he first made a name for himself with his intimate photographs of the Amish, which were considered a landmark in the photographic evolution of National Geographic. Allard went on to have work featured in some 30 articles, as well as in a number of National Geographic books.
