 Beckers & Piard were renowned photographers based in New York, at 264 Broadway. Their studio was established in 1849.
 Beckers & Piard played a significant role in the history of photography, helping to popularize and perfect the art of the daguerreotype. Their works continue to be studied and admired for their artistic quality and historical value.
 Some of their daguerreotypes are now preserved in prestigious collections, such as that of the Smithsonian National Portrait Gallery.
 The daguerreotype was the first photographic process, developed by Nicéphore Niépce and later Louis Daguerre, and introduced to the world (except the United Kingdom) by France in 1839. It is both a negative and a positive, hence its characteristic mirror effect. In the 19th century, they were also poetically called "mirrors that remember."
