About the author

Born in Savannah, Georgia, on January 21, 1813, John Charles Frémont became famous in the 1840s for leading surveying expeditions across the American West. His reports and maps reached a wide audience and helped shape how many Americans imagined places beyond the Mississippi, which earned him the lasting nickname “the Pathfinder.”

Frémont’s career quickly widened beyond exploration. He played an important role in events surrounding the U.S. conquest of California, later served briefly as one of California’s first U.S. senators, and in 1856 became the first presidential candidate of the new Republican Party. His antislavery stance made him a major national figure, even though he lost that election.

During the Civil War, he served as a Union general, though his command was controversial and short-lived. He died in New York City on July 13, 1890. Today he is remembered as an explorer, soldier, and politician whose adventurous reputation helped turn him into an American legend.
