This volume features about fifty photo historians from fifteen countries offering substantial and previously unpublished essays in honor of Dr. Heinz K. Henisch, the founding editor of the international quarterly History of Photography. The recognized authorities in the field, including Estelle Jussim, Ulrich Keller, Naomi Rosenblum, Mart Haworth-Booth, and others, are represented here and cover a wide range of topics from the earliest daguerreotypes to contemporary photography, with essays on nineteenth century practitioners, photojournalism, and twentieth-century aesthetics. This meaty collection of fifty-six essays is one no serious library, scholar, or student of photography should be without.
