Darius Ogden Mills
Darius Ogden Mills was a prominent American banker and philanthropist. For a time, he was Californias wealthiest citizen.
He was born in North Salem, New York, and his early career was as a bank clerk and retailer. He joined the California Gold Rush in December 1848, and founded a bank in Sacramento. He never invested in gold mining or silver mining directly, as he considered mining to be too speculative. He rather started ancillary businesses that supported the mining industry, such as banks and railroads. He was a part owner of the Virginia and Truckee Railroad, which was the only link from the Comstock Lode to the Central Pacific Railroad. The major share holder in the railroad was William Sharon, whom WIlliam Ralston had sent to Virginia City as representative of the Bank of California.
