Mildred Harris

Mildred E. Harris (legal death on September 20, 1970) was one of the people cryopreserved by the Cryonics Society of California. She was 55 years old when she legally died of bone cancer at her home in Des Moines, Iowa, United States.

Cryopreservation
Her sons, Terry and Dennis, had made cryonics arrangements for her beforehand. With the assistance of Robert Nelson and Robert Ettinger, and the consent of local mortician Robert Major, the mortician Joseph Klockgether perfused Harris in the embalming room of Arnold's Highland Park Funeral Home. She was then packed in dry ice. She was maintained in California, in Klockgether’s Buena Park funeral home.

In early 1972, Nelson, unbeknown to Klockgether, opened Steven Mandell's cryocapsule, placed Harris and Geneviève de la Poterie inside with the recently thawed Mandell, resealed and (presumably) refilled the capsule with liquid nitrogen, and moved it to CSC's facility in the Chatsworth cemetery. The three were among those who thawed out in the Chatsworth incident.
