Hippolyte Bayard (1801–1887) is often characterized as an underdog in the early history of photography. From the outset, his contribution to the invention of the medium was eclipsed by others such as Louis-Jacques-Mandé Daguerre (1787–1851) and William Henry Fox Talbot (1800–1877). However, Bayard had an undeniable role in the birth of photography and its subsequent evolution into a form of art. He was a pioneer in artistic style, innovator in terms of practice, and teacher of the next generation of photographers. Alongside an exploration of Bayard’s decades-long career and lasting impact, this volume presents—for the first time in print—some of the earliest photographs in existence. An album containing nearly 200 images, 145 of those by or attributed to Bayard, is among the Getty Museum’s rarest and most treasured photographic holdings. Few prints have ever been seen in person due to the extreme light sensitivity of Bayard’s experimental processes, making this an essential reference for scholars and enthusiasts of the very beginning of photography.
