Brigadier General Samuel P. Heintzelman


Samuel Peter Heintzelman (1805–80) was a Union general in the American Civil War. Born in Manheim, Pennsylvania, he graduated from the United States Military Academy at West Point in 1826 and served in the Mexican War (1846‒48). During the Civil War, he commanded a division in the First Battle of Bull Run (also called the First Battle of Manassas) and as a corps commander led Union attacks in the Peninsular Campaign of 1862 and in the Second Battle of Bull Run. Due to poor performance as a corps commander, he was reassigned to the Military District of Washington, where he remained for two years. He then transferred to the Northern Department in Columbus, Ohio, where he served until the end of the war. The image is from an album of mostly Civil War-era portraits by the famous American photographer Matthew Brady (circa 1823‒96) that belonged to Emperor Pedro II of Brazil (1825‒91), a collector of photography as well as a photographer himself. The album was a gift to the emperor from Edward Anthony (1818‒88), another early American photographer who, in partnership with his brother, owned a company that in the 1850s became the leading seller of photographic supplies in the United States. Dom Pedro may have acquired the album during a trip to the United States in 1876 when he, along with President Ulysses S. Grant, opened the Centennial Exposition in Philadelphia. Brady was born in upstate New York, the son of immigrants from Ireland. Best known for his photographs documenting the battles of the American Civil War, he began his career in 1844 when he opened a daguerreotype portrait studio at the corner of Broadway and Fulton Streets in New York City. Over the course of the next several decades, Brady produced portraits of leading American public figures, many of which were published as engravings in magazines and newspapers. In 1858 he opened a branch in Washington, DC. The album, which also contains a small number of non-photographic prints, is part of the Thereza Christina Maria Collection at the National Library of Brazil. The collection is composed of 21,742 photos assembled by Emperor Pedro II throughout his life and donated by him to the national library. The collection covers a wide variety of subjects. It documents the achievements of Brazil and Brazilians in the 19th century and also includes many photographs of Europe, Africa, and North America.
