Dr. Pietro was the Director of Amortality Research at Richard Byrd University.  He related to Douglas Best and High Normaj Jayne how Gene Klament had been only one of two patients out of ten to survive the first trial of Orag amortality therapy on Sapiens. The other eight either died of something similar to organ rejection or dissolved into protoplasm.

Pietro died the morning after his visit with Best and the High Normaj when the heating system in his house failed. Local authorities considered the incident a freak accident, but Best and Jayne suspected Pietro and his assistant were silenced.
