Thomas Oliver Larkin was an early California merchant, who served as U.S. Consul to the Province of California and U.S. Consul to the Republic of California, following the Bear Flag Revolt. His 2 letters to the president in June 1848 are two of the earliest communications of the discovery of gold in California sent to the East and his map of the Sacramento Valley was the first printed map to show the Gold Regions.
