James William "Jim" Denver (October 23, 1817 – August 9, 1892) was an American politician, soldier and lawyer. He served in the California state government, as an officer in the United States Army in two wars, and as a Democratic member of the United States House of Representatives from California. He served as secretary and Governor of the Kansas Territory during the struggle over whether or not Kansas would be open to slavery. The city of Denver, Colorado, is named after him. Early life and career James W. Denver was born near Winchester, Virginia. He attended public schools and moved to Ohio with his parents in 1830, settling near Wilmington.
