b. 1818
A traveler, photographer, and Gold Rush-era observer, this 19th-century writer is remembered for a lively firsthand account of the journey to California by way of Panama. His work captures the hazards, excitement, and rough politics of early mining-country life.

by J. M. (John M.) Letts
Born in New York in 1818, J. M. Letts is best known for California Illustrated (1853), a book drawn from his journey to California during the Gold Rush. Library of Congress material describes him sailing from New York via Panama in January 1849 and later writing about his arrival in San Francisco, his travels to Sacramento, and his time in the northern mining regions.
Sources on Letts also identify him as a photographer as well as an author. Archival records from the University of Oregon describe him as active in New York and the Mid-Atlantic region, and connect him with stereographic work alongside J. D. Eagles.
His writing stands out because it mixes travel narrative with sharp observations about everyday life in Gold Rush California, including camp politics, crime, mining methods, and encounters along the route west. Even with relatively few biographical details preserved, his book remains a vivid eyewitness record of a transformative moment in American history.
