From Famous Women: An Outline of Feminine Achievement Through the Ages With Life Stories of Five Hundred Noted Women. Written by Joseph Adelman, published 1926 by Ellis M Lonow Company:
Therese Elssler, sister of Fanny Elssler, was less graceful, but also exhibited great strength, boldness and agility.
She almost invariably danced with her sister, and used to efface herself in order to heighten the effect of Fanny’s more brilliant powers.
In 1850, after having retired from the stage, she became the wife of Prince Adalbert and was made Baroness von Barnim.
