Rough and Ready was settled in 1849 by a group of prospectors from Wisconsin who had headed west after news of Marshall's 1848 gold discovery in California. The party had named themselves the Rough and Ready Mining Company in honor of General Zachary “Old Rough and Ready” Taylor.
Upon arriving in California and discovering gold, they established the town of Rough and Ready at the discovery site, and began what would be a lucrative placer operation.
