Fidelia Heard

Fidelia Reed Heard was an American captain's wife who made important initial contributions to research on Heard Island, an Antarctic island, now part of Australia's Territory of Heard Island and McDonald Islands. The island is named for her husband, Captain John Jay Heard, who alongside Fidelia is credited with first spotting the landmass on November 25, 1853. The island's Fidelia Isthmus is named for Fidelia herself.
