Dr. Ferdinand Paul Mehrlich (May 9, 1905 – January 30, 1997) was an American food scientist known for his pioneering work on military nutrition and ration development. He served as the Scientific Director of the Quartermaster Food and Container Institute for the Armed Forces and later at U.S. Army Natick Laboratories.[1]
Early life and education
Born in Cincinnati, Ohio, Mehrlich earned his A.B. (magna cum laude) from Butler University, followed by graduate studies at the University of California. He completed his Ph.D. in Plant Physiology and Plant Pathology at the University of Wisconsin and undertook post‑doctoral research in mycology at Cornell University.[2]
Early career
In the early 1950s, Mehrlich served as Chief of the Food Acceptance Branch at the Quartermaster Food and Container Institute in Chicago, where he oversaw food preservation, packaging, and acceptance research.[2]
Work with Dole (Hawaiian Pineapple Company)
In the mid‑1940s, Mehrlich developed agricultural technologies while based in Honolulu working with the Hawaiian Pineapple Company (soon known as Dole). He invented and patented methods using plant hormones to improve pineapple yield and quality. Key patents include:[3]
Military rations development
Mehrlich later held senior scientific leadership roles in the U.S. Army:
As the Technical Director of the Armed Forces Food and Container Institute (AFFCI) to support the development of a lightweight “Ranger-type” ration tailored to Vietnamese troops. Mehrlich brought additional ration prototypes made from Vietnamese food ingredients, which were well received by the Army of the Republic of Vietnam (ARVN) and accepted by the Vietnamese government for further development. The project aimed to replace the U.S. Individual Combat Supplement Food Packet with a locally produced equivalent, improving suitability and supply logistics. Mehrlich briefed high-ranking officials, including President Ngô Đình Diệm, General Paul D. Harkins, the Vietnamese Joint General Staff, Military Assistance Advisory Group (MAAG) Vietnam, the Military Assistance Command Vietnam (MACV), and the United States Operations Mission (USOM). Vietnamese raw materials were shipped to AFFCI for processing into 500 pre-production prototypes, which were to undergo U.S. testing before being evaluated in Vietnam.[4]
Natick Laboratories and Ranger/LRP Rations As Director of the Food Laboratory at Natick, Mehrlich lead the development of the Ranger Ration and Long Range Patrol Ration. He spearheaded freeze-drying technology for field rations and directed creation of lightweight menus for Special Forces. Key patents include:[5]
Mehrlich's 1969 paper "Evolution of the Food Packet, Long Range Patrol" outlined the importance of long-term R&D, freeze-drying innovation, sensory evaluation criteria, and field usability; the LRP ration confirmed his view that the interplay of research and development leads to operational success. He noted that the ration’s rapid creation during the Vietnam War was made possible by prior research on mobile field rations and freeze-drying methods. The LRP ration was designed to be lightweight, compact, stable without refrigeration, and suitable for air-drop delivery. Natick researchers developed processes to maintain texture and flavor through freeze-drying, resulting in eight menu options by the late 1960s. Mehrlich also documented collaboration with commercial food manufacturers to adapt production methods, which reduced unit costs. He reported that the ration received favorable feedback from soldiers in the field.[6]
Recognition
Dr. Mehrlich received the Army Meritorious Civilian Service Medal for his work on the Ranger Ration from Brig General Woodrow W. Vaughn.[2]
