The Foxtrot (also: "Fox trot", "foxtrot", "fox trot") is a ballroom ance which takes its name from its inventor, the vaudeville actor Harry Fox. According to legend, Fox was unable to find female dancers capable of performing the more difficult two-step. As a result, he added stagger steps (two trots), creating the basic Foxtrot rhythm of slow-slow-quick-quick. The dance was premiered in 1914, quickly catching the eye of the talented husband and wife duo, Vernon and Irene Castle, who lent the dance its signature grace and style. It was later standardized by Arthur Murray, in whose version it began to imitate the positions of Tango.
