[2][3] She was the daughter of Nikolai von Galanta/de Galanta, from a Hungarian noble family Esterházy de Galántha.

[6] Galanta toured in the United States with the Ballets Russes in 1916, with Vaslav Nijinsky, Adolph Bolm, Flore Revalles, Lydia Lopokova, Olga Spessivtseva, and Valentina Kachouba, among others in the company of forty dancers.

[12][13] One critic found her performance distracting, saying "Ketty Galanta is vivid in the role of Anna; [her eyes] roll in a fashion so marvelous that one fears they may pop out of her head; consequently, the audience gasps in wonderment when it should merely feel the thrill of emotion.

[17] By 1922, Galanta moved to South America,[11] where she taught dance at her own studio[18] in Buenos Aires, Argentina.

[20] She was one of the founders of the Friends of Dance Association (AADA) there, along with fellow Ballets Russes dancer Tamara Grigorieva.
