One of the most controversial and romantic figures in American history, John C. Främont experienced a dizzying succession of public triumphs and humiliations. He made his name exploring the West, surveying, mapping, and describing the Rockies, the Great Basin, and Oregon country. Allan Nevins gives Främont full credit for his achievements as a topographer, soldier, and politician while noting how often his rashness attracted enemies and led to his downfall: to a court-martial for disobeying orders during the Bear Flag Rebellion, to a disastrous winter expedition in the San Juan Mountains, to his defeat as the first presidential candidate of the Republican party, to the loss of his Civil War command. Through sickness and health, poverty and wealth, his wife, the vivacious Jessie Benton Främont, stood by him. Their enduring romance occupies much more than the background in this absorbing story of his life. The dean of American historians, Allan Nevins won the Pulitzer Prize for his biographies of Grover Cleveland and Hamilton Fish.

As an explorer, John Charles Frémont led five expeditions into the American West--two of them disastrous. He was also one of California’s first two senators (1850), America’s first Republican candidate for president (1856), a Civil War general, and the territorial governor of Arizona (1878-83). But his life was one of rash and rebellious conduct against authority. During the Mexican War he claimed to be the military governor of California, which resulted in a court-martial in 1848. At the outbreak of the Civil War he reentered the army as one of four major generals, outranking even Ulysses S. Grant. However, when he antagonized President Abraham Lincoln by issuing his own emancipation proclamation in advance of the president’s, Lincoln relieved him of command. In this comprehensive biography, Andrew Rolle carefully examines the historical record with a psychobiographical approach that explores and explains the many irrationalities of Frémont’s character.
