Nathaniel Popper (born 1978/1979 in Pittsburgh, Pennsylvania) is a journalist for The New York Times covering finance and technology from San Francisco. He has previously worked for the Los Angeles Times and Lets Go Travel Guides. He graduated from Harvard University in 2002. Digital Gold: Bitcoin and the Inside Story of the Misfits and Millionaires Trying to Reinvent Money is the only book he has written, but he has published many articles. He first became interested in Bitcoin when he read an article that revealed how the Winklevoss twins, Cameron and Tyler Winklevoss, had been obsessed with obtaining a large number of Bitcoins. He then spent much of his time researching digital currencies, which then later led him to write Digital Gold.
