This magnificent work traces the development of photography in the State of Ohio from 1839 to the end of that century. Compiled and written by archivist and genealogist Diane VanSkiver Gagel, it also details the lives of hundreds of Ohio photographers who practiced their art, beginning with the introduction of the daguerrerotype in Ohio by Professor John Locke of the Medical College of Ohio. "Ohio Photographers, 1839-1900" thus provides a context for more fully integrating the visual, written, and oral records that comprise Ohio's history.
