DR. EDGAR L. PIRET,
77, a chemical engineer who invented the process used to make the Army's K-Combat Rations while employed at the University of Minnesota, died Sept. 24 at a hospital in Cambridge, Mass., after a stroke and heart attack.
He developed a process to make quick-dried, lightweight and portable food supplies -- K-Rations -- while at the University of Minnesota. Dr. Piret, who was a consultant with the 3M Co. from 1945 to 1965, also is credited with development of the Scotchlite Bead, a 3M product used in highway signs.
Dr. Piret also had been a counselor for scientific and technological affairs at American embassies in Europe and Japan. He helped organize programs in such areas as oceanography, space and medicine with several countries, including France, Belgium, Spain and Portugal.
