Clarence King was a well-known geologist in the late 19th-century, who became famous for his work surveying and studying the mountains of California. He was a man about town, a bon vivant who lived in gentlemen's clubs and hotels, and who was friends with men like Henry Adams and John Hay. He socialized in Washington, New York, and Newport's best circles, and traveled to Europe, where he collected art. He also had another identity--in Brooklyn, then Queens, he was known as James Todd. He had a wife, Ada Copeland Todd, who had been born a slave in Georgia, right before the Civil War. They had five children together (one died in infancy). Ada didn't find out about Todd's true identity until right before he died in the early 1900s, and the real story of his double life didn't come out until decades later, when Ada went to court to try to track down a trust fund Clarence had told her about.
