Ballets de Paris
Karel Shook, in his Elements of Classical Ballet Technique as Practiced in the School of the Dance Theatre of Harlem, describes Bower as a dancer “who did not perform as [a] ballet [dancer] per se, but who had classical technique and the elegance and carriage that go with it,” though she did perform professionally with a ballet company.
