That would make sense.

As the medium is not firmly identified, so the photographer remains even less certain. For some time the name of William DeRyee has been associated with these prints. DeRyee was a chemist, among other professions and trades, born in Bavaria in 1825, the family name Düry, and an immigrant to America in the late 1840's. In 1856, after travels, inventions, and prospecting, and on his way to mines in Arizona, DeRyee came to Texas and stopped in San Antonio. Here he began working as a chemist and, in connection with that, as a photographer. In 1859 he had a studio in the French Building, completed the preceding year at the southeast corner of Main Plaza and the subject of one of the photographs given by Mrs. Tylor. At various times in his career, DeRyee was associated with the artists Carl G. von Iwonski, Hermann Lungkwitz, and William C. A. Thielepape. The latter was also a musician and a post-Civil War mayor of San Antonio, whose home was on the grounds of the Alamo and pictured in a well-known Hermann Lungkwitz drawing, painting, and lithograph of Crockett Street.

In 1851, the Vance brothers purchased the Frontier Hotel for $500 and replaced the hotel with a two-story building that the Army could lease to house troops stationed in San Antonio. The facility continued to serve as a military headquarters until 1872 when the building was returned to the Vances.

The Vance House, a Greek Revival mansion, was built between 1857 and 1859 by James Vance, a local banker. Col. Robert E. Lee, walking under the grape arbors on its grounds, was said to have decided to resign a colonelcy in the United States (Union) Army and join the Confederacy, though he was fundamentally opposed to rebellion. Having made up his mind, he announced at a dinner in the Vance House’s great dining room: “If Virginia secedes, I shall stand with her.” Virginia seceded and Lee became the Commander of the Confederate armies. The Federal Reserve Bank currently stands on the site.
