RYDER, JAMES FITZALLEN (1826–1904)
American photographer
James Fitzallen Ryder, an American photographer for
most of the second half of the 19th century, learned the
daguerreian process in his hometown of Ithaca, N.Y. from
a self-styled “Professor” Brightly, who “assured me that
I was a promising subject and would make a mark as a
daguerreotypist,” Ryder wrote in his memoir.
In partnership with Brightly, Ruder operated daguer-
reian rooms in Ithaca, then became a traveling daguerre-
ian in southwestern New York, Pennsylvania and Ohio.
He opened a gallery in a vacant Mormon temple in
Kirtland for a time, and worked in Elyria, Ohio during
the winter of 1850. He then settled in Cleveland, where
he introduced the ambrotype to the city in 1855.
In 1862, under the commission of the Atlantic
and Great Western Railway, Ryder produced a two-
volume album of 129 photographs of the landscapes,
towns, stations and sheds, bridges, cuts, and tracks
associated with the company. By the late 1860s, Ryder
was Cleveland’s leading photographer.
In 1868 he helped introduce negative retouching
to the United States when he brought a retoucher from
Germany to the United States. Ryder was a founding
member of the Photographers Association of America
and became the group’s fi rst president in 1880.
