In 1942, medical officers serving in World War II combat zones reported the need for emergency transport splints. The metal ones they had used up to that point were causing wounded serviceman further injury while they were carried out of combat. The reason was that the metal amplified any vibrations from the stretcher bearers. Upon hearing this, Charles and Ray began experimenting with a new type of device to transfer war patients with injuries to their lower extremities.
The Eameses created their splints from wood veneers, which they bonded together with a resin glue and shaped into compound curves using a process involving heat and pressure. The slats between the wood allowed medical workers to pass cloth through the split and secure the patient’s leg.
Each of these splints bears an ink stamp with the words “Eames Process.”
