Aloisia Wagner (born 1906/1907, date of death unknown) better known with the stage name of Violetta, was born without legs or arms with a condition known as tetra-amelia syndrome. She had a lengthy career in sideshow performance. She was born in Hemelingen, Germany.
In April 1924 Violetta immigrated to New York City, United States from Bremen-Hemelingen, Germany, with her step brother, Karl Grobecker, and performed in sideshows as a singer, including Coney Island's Dreamland and the Ringling Bros. and Barnum & Bailey Circus. She moved herself by hopping from place to place on the bottom of her torso, and was able to manipulate objects with her mouth enough to comb her own hair, dress herself, thread a needle, and sew. Violetta was married and wore her wedding band on a gold chain around her neck.
