Emperor Norton
Joshua Abraham Norton (c. 1818 – January 8, 1880), known as Emperor Norton, was a citizen of San Francisco, California who in 1859 proclaimed himself "Norton I, Emperor of the United States" and subsequently "Protector of Mexico".
Born in England, Norton spent most of his early life in South Africa. He immigrated to San Francisco in 1849 after receiving a bequest of $40,000 (inflation adjusted to $1.1 million in 2015 US Dollars) from his father's estate, arriving aboard the steam yacht Hurlothrumbo. Norton initially made a living as a businessman, but he lost his fortune investing in Peruvian rice.
After losing a lawsuit in which he tried to void his rice contract, Norton became a less and less public figure. He reemerged in September 1859, laying claim to the position of Emperor of the United States. Although he had no political power, and his influence extended only so far as he was humored by those around him, he was treated deferentially in San Francisco, and currency issued in his name was honored in the establishments he frequented.
