With members of four generations involved in music and dancing, the Christensen brothers are considered the United States' closest equivalent to the European tradition of dance dynasties. Their story sheds light on the history of ballet in the 20th century, both through their accomplishments as dancers, teachers and company directors, and through their associations with movers and shakers of the dance world such as Lincoln Kirstein, George Balanchine, Sol Hurok and the Ford Foundation's W. McNeil Lowry. This triple biography encompasses the brothers' Mormon pioneer heritage, the circumstances that led them to enter vaudeville with a ballet act, and the rise and fall, especially in the American West, of companies with which they were associated for nearly six decades.
