Frank Veloz (1906–1981) and Yolanda Casazza (1908–1995) were a self-taught American ballroom dance team, husband and wife, who became stars in the 1930s and 1940s, and were among the highest paid dance acts during that era. They performed on stage in productions such as Hot-Cha!, which ran for 119 shows on Broadway in 1932. They also appeared in popular films such as Under the Pampas Moon (1935), The Pride of the Yankees (1942), Honeymoon Lodge (1943), Brazil (1944) and The Thrill of Brazil (1946), the latter of which is credited as being of major importance to the growth in popularity of Samba in America.
Veloz and Yolanda specialized in Latin ballroom dance styles, and opened their own chain of dance studios, where many middle-class people learned the art of ballroom dancing. The studios closed down in the mid-1950s as new forms of dance became popular. Veloz and Yolanda did much to legitimize ballroom dance as a performance art and invented the "Cobra Tango", a dance which interpreted a fight between a snake and a tiger. A full-length ballet written by their son Guy Veloz, An American Tango, is based on their life story.
