Mathew Brady (1823-1896) was one of the most prolific photographers of the nineteenth century, creating a visual documentation of the Civil War period (1860-1865). During the Civil War, Brady and his associates traveled throughout the eastern part of the country, capturing the effects of the War through photographs of people, towns, and battlefields. Additionally, Brady kept studios in Washington, DC and New York City, where many influential politicians and war heroes sat for portraits. The U.S. National Archives has digitized over 6,000 images from the series Mathew Brady Photographs of Civil War-Era Personalities and Scenes (National Archives's Local Identifier 111-B) and included them in our online catalog. The U.S. National Archives was established in 1934 by President Franklin Roosevelt, but its major holdings date back to 1775. The National Archives keeps only those Federal records that are judged to have continuing value -- about 2 to 5 percent of those generated in any given year. By now, they add up to a formidable number, diverse in form as well as in content. In addition to the photographs and graphic images described above, there are approximately 9 billion pages of textual records; 7.2 million maps, charts, and architectural drawings; billions of machine-readable data sets; and more than 365,000 reels of film and 110,000 videotapes. All of these materials are preserved because they are important to the workings of Government, have long-term research worth, or provide information of value to citizens.

In 1844, Mathew Brady opened a photography studio at the corner of Broadway and Fulton Street in New York. By 1845, he began to exhibit his portraits of famous Americans, including the likes of Senator Daniel Webster and poet Edgar Allan Poe. In 1849, he opened a studio at 625 Pennsylvania Avenue in Washington, D.C. Brady's early images were daguerreotypes, and he won many awards for his work. In 1850, Brady produced The Gallery of Illustrious Americans, a portrait collection of prominent contemporary figures. The album, which featured noteworthy images including the elderly Andrew Jackson at the Hermitage, was not financially rewarding but invited increased attention to Brady's work. When the Civil War started, he used a mobile studio and darkroom enabled vivid battlefield photographs. Thousands of war scenes were captured, as well as portraits of generals and politicians on both sides of the conflict, though most of these were taken by his assistants, rather than by Brady himself. After the war, these pictures went out of fashion, and the government did not purchase the master-copies as he had anticipated. Brady's fortunes declined sharply, and he died in debt.

The Americana collection of Marian Sadtler Carson (1905-2004) spans the years 1656-1995 with the bulk of the material dating from 1700 to 1876. The collection includes more than 10,000 historical letters and manuscripts, broadsides, photographs, prints and drawings, books and pamphlets, maps, and printed ephemera from the colonial era through the 1876 centennial of the United States. It is believed to be the most extensive existing private collection of early Americana. The collection includes such important and diverse historical treasures as unpublished papers of Revolutionary War figures and the Continental Congress; letters of several American presidents, including Thomas Jefferson; a manuscript account of the departure of the first Pony Express rider from St. Joseph, Mo.; and what may be the earliest photograph of a human face. Many of the rare books and pamphlets in the collection pertain to the early Congresses of the United States, augmenting the Library's unparalleled collection of political pamphlets and imprints. The Carson Collection adds to the Library's holdings the first presidential campaign biography, John Beckley's Address to the people of the United States with an Epitome and vindication of the Public Life and Character of Thomas Jefferson, published in Philadelphia in 1800. The book was written to counter numerous attacks against Jefferson's character, which appeared in newspapers and pamphlets during the bitter election campaign. The Rare Book and Special Collections Division shares custodial responsibility for the collection with the Library's Geography and Map Division, Music Division, Prints and Photographs Division, and the Manuscript Division.

Langenheim Brothers was a photography studio founded in Philadelphia in 1846 by William and Frederick Langenheim. They were known for their innovative techniques and pioneering work in the field of photography. The Langenheim Brothers were among the first photographers to use the daguerreotype process and also experimented with stereoscopic photography, which produced 3D images. The Langenheim brothers' work was highly regarded and they received numerous awards for their photography, including a gold medal at the Great Exhibition in London in 1851. They also photographed notable figures of their time, such as Edgar Allan Poe and Abraham Lincoln. The Langenheim Brothers' studio continued to operate into the early 1900s, and their legacy lives on through their contributions to the development of photography as an art form.
