Member of the Mohegan Pequots and played an integral part in preserving the Mohegan historical records and oral traditions.

Emma Fielding Baker was posthumously elected as the Medicine Woman of the Mohegan Tribe in 1992. Her protege and niece, Medicine Woman Gladys Tantaquidgeon, was installed in that position at the same time.

Emma's contributions include revitalizing the Mohegan Green Corn Festival (nicknamed "The Wigwam") in 1861 to unify the Mohegan people in an annual celebration, as their reservation was largely disbanded in that year. Emma organized this event as the President of the Mohegan Church Ladies Sewing Society.

By the late nineteenth century, Emma had also been elected by the tribe to represent the group in Hartford, Connecticut regarding land disputes, particularly involving Indian burial desecration. Moreover, Emma was responsiblefor regulating tribal land divisions and maintaining Mohegan historical records and oral traditions.
