Eugenie Peterson (Latvian: Eiženija Petersone, Russian: ??????? ?????????? ????????; May 12, 1899 – April 25, 2002), known as Indra Devi, was a pioneering teacher of yoga as exercise and an early disciple of the "father of modern yoga", Tirumalai Krishnamacharya.
Her popularization of yoga in America through her many celebrity pupils in Hollywood, and her books advocating yoga for stress relief, earned her the nickname "first lady of yoga".
Her biographer Michelle Goldberg wrote that Devi "planted the seeds for the yoga boom of the 1990s".
