Albert Charles Peale (April 1, 1849 - December 5, 1914) was a geologist, mineralogist, and member of the U.S. Geological and Geographical Survey of the Territories (also known as the Hayden Survey). He studied at Philadelphia's Central High School and trained to become a physician, earning a medical degree though never practicing medicine. In 1871, he joined Hayden and would spend most of the next thirty years with the Survey of the Territories and its successor, the U.S. Geological Survey. He later worked as a paleobotanist at the Smithsonian. Several natural features in Wyoming, Idaho, and Utah are named for him.
