Gavrielia Papagianni was a Greek Orthodox nun, born in Constantinople in 1897, who dedicated her life to the service of the vulnerable. A highly educated woman, she was the second female student admitted to a Greek university and practiced as a physiotherapist before entering monastic life at age 60. Throughout her diverse career, she provided medical care to impoverished communities in India, East Africa, and the United States. She was later recognized as an elder, or Gerontissa, for her spiritual guidance and continued assistance to the sick.
