Diamonds in their Dreams (Only): The Great San Francisco Diamond Hoax of 1872
Tuesday, March 10 @ 7:30 pm - 9:00 pm
One of the most notorious mining scams in U.S. history, now called the “great diamond hoax,” took place in San Francisco in 1872. At the time, the San Francisco Chronicle described the scam as “the most gigantic and barefaced swindle of the age.” Victims included some of California’s biggest bankers and businessmen (including William Ralston of the Bank of California) and many other people. Harold Tuchfeld will talk about the incident and many of the people who were fooled until the scam was exposed by a brilliant young geologist, Clarence King, and his survey team.
Harold Tuchfeld practiced as an environmental geochemist and project manager for more than 20 years at major civil/environmental engineering consulting firms. He now works as a manager at a global hi-tech corporation headquartered in Sunnyvale.
