Titian Ramsay Peale (November 17, 1799 – March 13, 1885) was an American artist, naturalist, and explorer. He was a noted scientific illustrator whose paintings and drawings of wildlife were known for their beauty and accuracy. He participated as a naturalist in several scientific surveys, in particular he accompanied Stephen Harriman Long in 1819 to explore the Rocky Mountains and later served on the United States Exploring Expedition (1838-1842).
Peale was born on November 17, 1799 in Philadelphia, the youngest son of noted artist and naturalist, Charles Willson Peale. He was first exposed to the study of natural history while assisting his father on his many excursions in search of specimens for the Peale Museum. The family moved to Germantown, Pennsylvania, outside of Philadelphia, where he began collecting and drawing butterflies and other insects. Although some of his butterfly and moth illustrations were ultimately published, the majority remained unpublished until recently. Like his older brothers Raphaelle, Rembrandt, and Rubens Peale, Titian helped his father in the preservation of the museum’s specimens for display, which included contributions from George Washington, Thomas Jefferson, and the Lewis and Clark Expedition.
