Photographic plates preceded photographic film as the target medium of photography. Dry plate, also known as gelatin process, is an improved type of photographic plate invented by Dr. Richard L. Maddox in 1871. By 1879, the first dry plate factory was established. With much of the complex chemistry work centralized into a factory, the new process simplified the work of photographers, allowing them to expand their business.

The D.C. National Guard came about in part due to the efforts of President Thomas Jefferson, the first President to spend his term in Washington, D.C. On October 30, 1802, the D.C. National Guard held its first muster. President Jefferson hand-selected his new officers and was known to enjoy attending drills. A year later, Congress officially recognized the organization.
